INTRODUCTION The ThunderBolt™ Storm Detector is designed to detect and track thunderstorm activity within 75 miles of your location. It provides detection warning via text messages on the two-line LCD (Liquid Crystal Display), the red and green indicator LEDs (Light Emitting Diode), and an audible tone. All of the operations and functions for the ThunderBolt are selected from the main menu, and basic storm detection is automatic once the unit is powered on. IMPORTANT! The ThunderBolt uses the latest electronic and computer technology to detect and track thunderstorms. However, thunderstorms can be a rapidly changing weather phenomenon, and the information provided by the ThunderBolt should always be used in conjunction with other sources of information. Remember that the ThunderBolt detects ACTIVE storms, and cannot predict when or where a particular storm may form, and/or where the first lightning stroke occurs.

GENERAL OPERATION The ThunderBolt detects and tracks the motion of storm cells by detecting the lightning activity within the cell. The unit is capable of detecting multiple storm cells within its 75-mile operating range, and is also capable of identifying squall lines and severe storms. (Super-cells are severe thunderstorms that are typically larger and more violent than normal storms. They comprise approximately 10% of all thunderstorms.) 1

Once in basic Storm Scanning mode, the ThunderBolt™ warns of any detected thunderstorm activity using text messages displayed on the LCD. Depending on the exact type of weather situation being detected, the information is displayed using a repeating series of two-line messages on the screen. These messages cycle approximately every 10 seconds so that any particular message will reappear within a short period. It is important to remember that the ThunderBolt continually accumulates data from the ongoing storm activity and that more accurate information can be displayed with more data in the computer memory. This makes it important to have the ThunderBolt operating for as long as possible before storm activity is nearby. Don’t wait until you think storms are close before turning on the unit! If the ThunderBolt is turned on with Thunderstorm activity already close by, it may take several minutes for the most accurate information to be calculated and displayed. IMPORTANT! Anytime the ThunderBolt displays detected storm activity immediately after power on, you should take extra precautions until enough data has accumulated to give an accurate location of the storm. Storm activity should be assumed to be LOCAL and appropriate precautions taken until at least fifteen minutes of storm data has been allowed to accumulate. This is especially important if the APPROXIMATE RANGES displayed are 20 miles or less! Once a storm approaches within 8 miles of the user location, the ThunderBolt warns that the storm is now LOCAL. It will

2

maintain this warning until the detected storm activity recedes to a distance of more than 8 miles. While the storm is local, the ThunderBolt™ will calculate and display the estimated time for the storm to clear. Note this is only an estimate! The storm motion may change while still in your vicinity, and the time for it to clear to a safe distance may change quickly! IMPORTANT! Note that storms may form directly over your location, and that advance warning of these storms may be very limited! The ThunderBolt continually analyzes the intensity of the storm activity it detects, and attempts to provide additional warning about the presence and approach of both squall lines and super-cells. Once detected, warnings for these types of storms are displayed in the LCD. Both types of storms are capable of producing high winds, severe rain, and tornadoes. Extreme caution should be taken if these warnings are displayed. Also note that storm cells may evolve quickly from a normal cell into these more dangerous forms of weather. Always consult your local weather information sources, if available, when the threat of these types of storms are present. IMPORTANT! Keep in mind that all of the approach speeds and estimated arrival times are based on data that the ThunderBolt accumulates over periods of time. Thunderstorms can change both their intensity and activity on very short notice. The information displayed by the ThunderBolt must be used as an approximation that can change quickly as the storm changes.

INSTALLATION AND SET-UP The ThunderBolt™ is designed to operate either vertically (hand-held, using the wall-mount, or using the optional desk stand), or lying flat on a horizontal surface. The unit will NOT perform properly if oriented on its side. The ThunderBolt contains special software routines for detecting and minimizing false triggering from non-storm sources. A special noise-test feature should be selected from the main menu when first installing the ThunderBolt in a new location. This routine will take 15 minutes to run, during which it detects and maps all the regular sources of electromagnetic noise in the vicinity. Once returned to normal operation, the ThunderBolt will ignore these regular noise sources. The ThunderBolt also continuously monitors the background electromagnetic noise level during normal operation. If the high local noise level lasts long enough to interfere with normal storm detection, the ThunderBolt will display a warning message that indicates the unit must be relocated for accurate operation. This same message will be displayed during the normal Noise Test routine if background noise level conditions are detected that will not allow proper operation and storm detection. IMPORTANT! If the message "WARNING:HIGH BACKGROUND NOISE" is displayed, turn the unit off, move it to a different location, and restart. As soon as any local storm activity has cleared, the Noise Test routine should be selected and run from the main menu. Until the Noise Test has been rerun, the accuracy and detection sensitivity of the unit may be reduced. 4

The ThunderBolt™ is powered by a single 9-volt battery. It may also be powered by using the 115V-AC (or 220V-AC) adapter available from Spectrum Electronics, Inc. NOTE: The use of a non-specified adapter may cause inaccurate or improper operation of the unit, and may damage the power supply circuitry. Should you have any questions about the use or operation of your ThunderBolt, call Spectrum Electronics, Inc. at the tollfree customer service number shown in this manual between 9a.m. and 5p.m. EST. Or you may post a message for a customer service representative by logging on to the ThunderBolt website at www.spectrumthunderbolt.com IMPORTANT! Remember that the ThunderBolt is designed to detect and track storm cells and squall lines, not individual strokes of lightning. A single stroke of lightning contains variations due to amperage of the stroke, polarity, and orientation to the ground. All of these factors make it more dependable and accurate to analyze, detect, and track the entire storm cell as it moves. Thunderstorms are also large (6-10 miles across) with lightning activity appearing in different places within the body of the storm, often simultaneously. Once a storm is local, lightning can appear at ANY TIME at your location! Take defensive action before this situation develops! BASIC OPERATION 1. Battery Installation The ThunderBolt operates on one standard 9V battery. Clip the connector over the terminals on the battery and securely close the battery compartment door on the back of the unit. (NOTE: 5

The compartment door has been designed to provide a secure fit to withstand rugged use. As a result, the compartment door may initially be stiff and difficult to open. By using the bottom of your palm, place downward pressure on the door at the point between the EX. SPK. and 9V DC jacks, and then push the door away from the unit. The compartment door will become easier to open with each successive opening.) Remaining battery life is constantly monitored by the computer. A LOW BATTERY warning message is periodically displayed once remaining battery life drops below approximately 5-7 hours. The battery should ALWAYS be replaced as soon as possible once the LOW BATTERY warning message is displayed. 2. External AC Adapter The ThunderBolt™ may be powered by an approved low-noise external adapter. The adapter jack is labeled “9V DC” and is located on the back of the unit above the battery compartment door. If you occasionally detect incidences of false triggering when using the system on your AC Adapter, the problem is most likely voltage spikes on your AC power. Whenever possible, we suggest you use standard surge protection to filter out the noise. 3. Power ON/OFF Pressing the ON/OFF button on the front of the unit turns the power on. The MAIN MENU appears on the display, and the green LED, located behind the lens at the top of the unit, blinks to indicate normal operation. The SCROLL UP/DOWN buttons are used to move up and 6

down the items on the MAIN MENU. Selecting an item from the menu is done by moving the blinking cursor to the numbered item desired, and then pressing the ENTER button. After initial power-up, the ThunderBolt™ automatically begins normal storm detection if no other button is pressed within 10 seconds. The ThunderBolt is programmed to automatically turn off after approximately five hours if no buttons are activated. This is meant to conserve battery life if the unit is accidentally stored while turned on. This automatic-off feature is disabled if the unit is being powered by the external 120V-AC adapter. To manually turn off the unit, press the ON/OFF button and hold the button until a short alarm sound is emitted from the unit (approximately one second)—this delayed deactivation prevents the unit from getting turned off inadvertently. 4. Normal Operation There are five user-selectable choices on the MAIN MENU: 1. STORM DETECT 2. ALARM RANGE 3. ALARM MODE 4. SENSITIVITY 5. NOISE TEST Remember that you can only view two lines of the menu at any one time. Use the SCROLL UP or DOWN keys to move through the menu options. Once in SCANNING mode, pressing and releasing either of the scroll keys will display the menu. Once in the menu, the unit will automatically shift to SCANNING mode if no other buttons are pressed within 5-7 seconds. 5. Tone Operation The tone may be turned on or off any time the normal scanning screen is displayed by pressing the Tone ON/OFF button

7

on the front of the unit. To turn the tone off once storm activity has been detected, first power off the unit using the ON/OFF button. Then restart the unit and wait for the scanning screen to reappear before pressing the Tone ON/OFF button. A “TONE IS OFF” message will briefly be displayed and the unit will automatically return to normal scanning operation. The unit will quickly resume the current storm display. STORM DETECTION Selecting STORM DETECT puts the unit into normal storm detection. Once the unit is powered on, it automatically goes into STORM DETECT unless another key is pressed within 5 seconds. Once SCANNING, the cursor will move back and forth and the selected SENSITIVITY (normal or high) will be displayed. To change any of the user settings, press and release either of the scroll keys to call up the main menu. (Remember that you may have to scroll down to find the desired menu item for selection. Only two lines of the menu will be visible at any one time.) Once initial storm activity is detected, the screen will display a warning that strikes have been detected, and then the range in miles to the last CLOSEST strike detected. This information will be displayed and updated until enough data has been accumulated to display the range to the leading edge of the storm, along with indication of storm motion. The time required for accumulation of this data may vary depending on the actual levels of activity within the storm. If no movement toward you has been detected, a NO APPROACH DETECTED message will 8

be displayed along with storm distance. If the storm is approaching, the storm speed, along with Estimated Time of Arrival (ETA) in you area will be displayed. IMPORTANT! The ETA displayed is the estimation of when the leading edge of the storm activity will reach within 8 miles of your location. This may happen without any obvious signs of storms being directly overhead. Once any part of storm cell activity has been detected within 8 miles of your location, the screen display will indicate STORM IS LOCAL. This means that lightning activity directly overhead is now possible at any moment, and extreme precautions should be taken! Once a storm has become LOCAL, an estimated TIME TO CLEAR will be displayed. This time estimate is broken into 15-minute segments, and is updated as storm data continues to be collected. The estimate displayed may change or run longer based on the actual storm activity. This will often happen with storms that develop directly overhead with very little associated movement. IMPORTANT! Remember that most storms detected at ranges greater than 20 miles will appear to be approaching, and will be given an ETA, until enough data is accumulated to be certain of passing safely out of local danger range. In actual operation, this will mean that storms detected at long range will appear to gradually veer off from your location. In actuality, the ThunderBolt™ may warn of a potential storm strike until enough data indicates there is little or no possibility of a direct hit. For most storm situations, the ThunderBolt will be able to determine the likelihood of a direct hit or near pass from the storm by the 9

time it has closed to within 15-20 miles. Storms displaying ranges of less than 20 miles and ETAs of less than 30 minutes are HIGH LEVEL threats and should trigger maximum safety responses. The ThunderBolt™ constantly analyzes the incoming data for signatures of squall lines and super-cells. If either of these conditions is detected, a text message appears on the screen. Both of these weather patterns are HIGH LEVEL threats for high winds and possible tornado activity. Extreme caution should be exercised when these conditions are approaching your location. Once storm activity approaches within 8 miles of the user’s location, the screen displays a STORM IS LOCAL warning. The ThunderBolt then calculates the expected time for storm activity to clear the user’s location. (Clearing a location means NO detected storm activity within eight miles for 15 minutes. If any activity at all occurs while the storm is local, the Time to Clear will reset itself.) IMPORTANT! The Time to Clear is updated continuously using actual storm speed, as well as the approach of storms outside the 8-mile local zone. Keep in mind that these factors may cause the Time to Clear estimate to change and lengthen once it begins. Also note that this is ONLY intended as an estimate of the time necessary to completely clear dangerous activity from your location. Storm motion and activity can occur faster than the ThunderBolt can accumulate enough data for accurate estimates.

ALARM RANGE Selecting this option allows the user to choose the warning range for activation of the red LED and the audible tone. Warning ranges are selected by using the SCROLL UP/DOWN buttons to toggle the displayed range in miles to the value desired. Pressing the ENTER button stores the value in memory. Once stored, these values will be used every time the unit is operated until changed. NOTE: The audible tone may be turned on or off at any time by using the front panel button. This will not change the alarm range stored in memory. Please note: each time the unit turned on, the audible tone will be on, and must be turned off manually. ALARM MODE Selecting this option allows the setting of an additional trigger distance for an audible alarm with a faster tone rate. This feature allows the ThunderBolt™ to automatically increase its alarm level as a storm approaches to a closer distance than the range selected for normal storm detection. SENSITIVITY Selecting this option allows the user to select either a HIGH or NORMAL storm detection sensitivity. HIGH sensitivity will maximize the distance at which storms are detected and tracking begins. It will tend to plot storms as closer and approaching faster than they might actually be, and should be used in situations where maximum caution and time are required to prepare for storm arrival. The HIGH sensitivity setting may also be used in certain indoor applications where the surrounding building may be reducing the received signal strength. 11

The NORMAL setting produces greater accuracy in storm tracking and speed calculation, but increases the time between a storm first being detected, and a calculated speed and ETA being displayed on the screen. BACKGROUND NOISE TEST This option runs up to a 15-minute sampling routine which detects and maps the periodic noise sources in the planned operating location for the ThunderBolt™. Once completed, this allows the unit to ignore regular, non-storm electromagnetic interference (EMI) in the environment. If the background EMI at the selected location is too high to allow normal storm detection, a warning message will be displayed, indicating that the unit must be moved to a different location for proper operation. Otherwise, the unit will automatically return to the main menu. NOTE: Pressing ENTER, or any other button, will stop the noise test routine before completion. No data will have been stored and the test will need to be run from the beginning at a later time. The Noise Test should be rerun periodically to ensure accurate operation. IMPORTANT! The noise test MUST be run when no real storm activity is occurring within 50 miles of your location. Running the noise test with actual storm activity within range will introduce errors and inaccuracy to the normal operation of the ThunderBolt, and may decrease the operating sensitivity of the unit.

THUNDERBOLT LCD TEXT MESSAGES What do they mean? ThunderBolt™ has been programmed to communicate certain messages during specific weather conditions. In normal operation, the user will see a repeating series of messages specific to that situation. The following list describes the most common text messages the user will encounter using the ThunderBolt, along with a brief explanation. These explanations may answer questions the user may have during certain weather conditions. It is important to note that due to space limitations, as well as memory limitations, ThunderBolt provides messages programmed into the software and cannot necessarily elaborate due to such limitations. SCANNING SENSITIVITY HIGH ThunderBolt is scanning and has not detected any storm activity. This option provides the fastest possible information, sacrificing accuracy for speed. The information will gradually become more accurate as the unit gathers more data. Use this option in situations where maximum warning time is required to prepare for storm arrival, or in certain indoor applications where the surrounding building may be reducing the signal strength. SCANNING SENSITIVITY NORMAL ThunderBolt is scanning and has not detected any storm activity. When using this option, a longer period of time is necessary for specifics of any storm activity to be indicated. 15

NOTE: Both HIGH and NORMAL modes are effective and selection by the user should be made based on preference and/or application needs. WARNING! STRIKES DETECTED ThunderBolt™ has detected initial lightning activity. The next screen will follow: CLOSEST ACTIVITY ______ MILES The ThunderBolt has detected storm and is in the process of initial ranging. The display represents the closest detected stroke during the period of initial data collection. STORM ACTIVITY ______ MILES ThunderBolt has plotted the storm location. Storm approach speed and ETA (estimated time of arrival) will follow if the storm is approaching. SEVERE STORM ThunderBolt has detected a severe storm. Please take proper precautions, including checking other weather sources for additional information and advisories. SQUALL-LINE OR MULTIPLE STORM CELLS ThunderBolt has detected the presence of squall lines or multiple storm cells. ThunderBolt provides storm information closest to the user. 16

APPROACH SPEED ____ MPH ThunderBolt™ has determined that the storm is approaching the user at the indicated speed. This information does not always mean the storm will reach the user, as storms can sometimes change direction or dissipate. STORM ETA _______ MINUTES ThunderBolt has calculated the storm distance and approach speed and determined, based on current conditions, that the storm will reach striking distance of the user in the time estimated on the screen. WARNING STORM IS LOCAL When this message appears, seek safe shelter. The storm has moved within eight (8) miles and is now within striking distance of the user. NOTE: the user may not yet hear or see lightning (perhaps looking at blue sky/non-threatning conditions) as the storm may be on the edge of the eight mile range (well beyond the range of seeing or hearing storm activity). This represents one of the most dangerous situations (commonly referred as the Bolt out of the Blue), as the user’s common sense may disregard the ThunderBolt warning due to perceived conditions. WARNING: 30% of all lightning victims are struck on the front edge of the storm. Rely on ThunderBolt and other weather sources and seek safe shelter during this warning.

17

WARNING STORM LOCAL ____ MILES This is not a common screen and will appear only when a storm develops within the eight mile LOCAL range. There will not be any previous storm warning on the unit because the storm developed within this range. This occurrence is more common in subtropical and tropical regions when small storm cells can develop rapidly during summer season. TIME TO CLEAR ____ MINUTES Once storm activity has become LOCAL (within eight miles of the user), the ThunderBolt™ will indicate, based on current conditions, the amount of time it will take for the storm to safely clear the eight mile range. The unit is limited to three time frames (15, 15-30, and 30 minutes). Once this time appears, ThunderBolt internally begins a countdown of this time. If during this countdown, the ThunderBolt detects any new lightning strokes within the eight mile range, it will automatically reset the time back to the time it originally indicated. Therefore, the TIME TO CLEAR time can be greater than indicated as the unit detects new activity. Once the unit has completed its internal TIME TO CLEAR countdown, it will resume normal scanning activity (indicated on the screen) and it is safe to resume outdoor activities.

18

QUESTIONS ABOUT OPERATION The ThunderBolt™ indicates STORM IS LOCAL, but no visual indication of a storm nor any audible thunder occurs. Most likely, this is indicative of very low intensity electrical activity coming from a cloud formation(s), but may not be (or become) a storm as we typically define a storm. While this is a common phenomenon in subtropical or tropical climates, it can also occur most anywhere. It represents one of most dangerous weather situations because there is no visual or audible danger. Yet a "bolt out of the blue" can occur from this situation, resulting in many of the annual lightning deaths and injuries suffered worldwide. This is an instance when you should not put your faith in your own common sense. Use the ThunderBolt, as well as all other weather sources available to you, to help make the safest decision in this situation. Another possible reason may be the location of the ThunderBolt. Is the unit being used near a computer or other electronics? These and other high noise sources can cause the ThunderBolt to false trigger. Move the ThunderBolt away from the possible source of interference and re-run the noise test routine. I hear thunder and/or see lightning, but ThunderBolt is not indicating “Storm is Local.”

19

There are several possible reasons for this occurrence. 1. Unit was turned on after activity has approached the area. ThunderBolt™ is designed to gather storm data and provide the user with storm information based on the data it has analyzed. If turned on at first indication of storm activity, it will take it time (which will vary depending on the intensity of the storm) to gather enough data to provide accurate information. ThunderBolt will provide the most useful and accurate information when turned on and in use through the duration of all outdoor activity. 2. Unit is getting used at a new location and the noise test has not been conducted. A noise test should be conducted when moved to a new location to assure most optimal operation. WARNING: Do not conduct a noise test during storm activity, as this will DESENSITIZE your ThunderBolt. 3. Activity may be cloud-to-cloud lightning. Cloud-to-Cloud lightning are lightning strokes within the cloud, but not emitting strokes to the ground. At night, such activity can literally light up the sky. There may also be audible thunder with this activity (generally a low rumble). The ThunderBolt, recognizes this activity, but will not indicate it because it is not necessarily a dangerous situation. ThunderBolt will provide detection warning should the activity develop into cloud-to-ground lightning strokes. This is a situation where your common sense should be exercised, and precaution becomes the prudent thing to do.

20

4. Activity may have developed within local range and low intensity. A common occurrence in subtropical or tropical climates, or any region similar to Florida. This is a situation when too little data has occurred for the ThunderBolt ™ to respond quickly. Again, this is a situation when your common sense should be exercised and precautionary measures become prudent. 5. If none of the above explanations appear to apply, please call Customer Support at Spectrum Electronics toll free at (877) 738-7330. Storm appears to have cleared, but the ThunderBolt continues to display “Time to Clear” information. Storm may be out of your visible or audible range (4-6 miles or less), but may still be within 8 miles. CAUTION: 60% of all lightning victims are struck after the storm has passed. ThunderBolt’s Time to Clear feature has been designed to count down the estimated Time to Clear time before it goes back to normal scanning mode. Should any lightning stroke occur within 8 miles during this countdown, ThunderBolt will automatically reset the Time to Clear back to the original estimated time (15 minutes is the minimum time increment). Due to this feature, it is possible the activity has cleared while ThunderBolt is in its countdown. To verify, you can turn the unit off for 30 seconds to reset and then turn it on. ThunderBolt will go into a scanning mode; if no activity is detected then the storm has most likely cleared the “local” area.
