__________________System 2000_________________ 16 CHANNEL WIRELESS MICROPHONE AND RECEIVER The 16 Channel Wireless Microphone, Receiver and Charging Cradle are custom designed units that allow for wireless PA communication from anywhere on the coach. The unit consists of a receiver mounted in the parcel area directly behind the driver, and a rechargeable hand-held microphone and charging cradle. The receiver has a front mounted power button and LED indicator. When the button is pushed in, the power is on and the indicator illuminates. When the microphone is keyed a RF LED illuminates indicating the presence of a RF signal. An adjustable level (volume) control is provided to set the relative audio level. When the microphone is spoken into the audio level is indicated on five vertical LEDs. The receiver also has a diversified antenna system (dual antenna). This system switches between the two antennas to locate the strongest signal from the microphone. The antenna in use is indicated by lighting either the A or B LED. Both the receiver and the microphone have manual channel selectors. The channel is set with a small screwdriver and both the channel selectors on the microphone and receiver must match. The unit is a FCC approved device operating on the following 16 frequencies: 175.000 MHz 175.300 MHz 175.600 MHz 175.900 MHz
176.200 MHz 176.500 MHz 176.800 MHz 177.100 MHz

The Changer is controlled by the Panasonic Radio. The radio controls include Disc control features including Disc selection and Disc scan. Individual track functions include: Track Selection, Track Search, Track Repeat, Random Track, and Track scan.
Features: •
The CD Changer receives power (+12VDC) and all control signals from the radio through a single connector on the side of the unit. An external memory line is also provided.
•
The CD magazine can be removed from the unit (via the eject button) for convenient storage and security.
•
Compact size and easy mounting keeps the Parcel rack clear and open for baggage storage.

System 2000 Tuner 2000 Operations: •
The Tuner is capable of receiving both UHF and VHF television broadcasts and displaying them on the monitors. The unit is typically mounted on the side of the VCP, located in the front left parcel area behind the driver. The tuner has a two terminal “Y” connector for power and is connected “in-line” with the power cable going to the VCP (both 12 and 24 VDC models are available). For optimum reception, the tuner requires an external UHF/VHF antenna to be connected to the Antenna in Jack, also located on the rear of the unit. The received channel is split internally into separate audio and video signals. The video and audio outputs of the tuner are connected to the video and audio inputs of the VCP for display on the monitors. The tuner has a red LED that indicates that power is present. This LED becomes brighter in intensity when the unit is turned on via the power button on the front. There are three channel control buttons labeled AUTO, CHANNEL UP, and CHANNEL DOWN also located on the front of the unit. The AUTO Channel button is pressed to automatically program the unit to receive broadcast signals of sufficient strength to produce a viewable picture. The CHANNEL UP and CHANNEL DOWN buttons increment or decrement respectively the programmed channels within the unit’s memory. As the coach travels to different locations, the auto-programming feature may need to be repeated to update the tuner memory for the local broadcast area.

CHECK / SOLUTION Activate the Video system via the button labeled VIDEO on the Control Head (700227). Display will indicate "VID". Verify power connections to relay and any external current protection devices, i.e. fuses or circuit breakers Activate the Video System via the Control Head. Measure the Voltage on both sides of the Video relay's coil. The side connected to the cable, orange wire, should measure approximately 0 Volts. The opposite side should measure power (+12 or +24V depending on relay used). Relay should energize. If these voltages are present but the relay does not energize, replace the relay. Verify that the orange wire is connected to the relay coil. Activate the Video System (as previously described). Measure Voltage levels at the relay coil. If the orange wire does not measure near 0 Volts (less than 1V), and all other connections are correct, replace or repair the Control Head (700227). If power is being switched by the relay, verify that it is also present at the parcel racks, were the monitors connect to it. If not, repair or replace power wire.
