Electromagnetic environment - guidance Portable and mobile RF communications equipment should be used no closer to any part of the

Ritter Excellence Chair-mounted Dental Unit, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter. Recommended separation distance Conducted RF

Where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in metres (m). Field strengths from fixed RF transmitters, as a determined by an electromagnetic site survey, should be less than the compliance level in each frequency b range. Interference may occur in the vicinity of equipment marked with the following symbol:

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

a ) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Ritter Excellence Chair Mounted Dental Unit is used exceeds the applicable RF compliance level above, the Ritter Excellence Chair Mounted Dental Unit should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Ritter Excellence Chair Mounted Dental Unit. b ) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communications equipment and the Ritter Excellence Chair-mounted Dental Unit The Ritter Excellence Chair-mounted Dental Unit is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the Ritter Excellence Chair-mounted Dental Unit can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Ritter Excellence Chair-mounted Dental Unit as recommended below, according to the maximum output power of the communications equipment.
