The AR-9800 Synergy
RF
System is intended for use in the electromagnetic environment specified
below. The customer or the user of the AR-9800 Synergy
RF
System should ensure that it is used
in such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the Model
AR-9800, including cables, than the recommended
separation distance calculated from the equation

manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey

should be less than the compliance level in each
frequency 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 Model AR 8305 is used exceeds the
applicable RF compliance level above, the Model AR-9800 should be observed to verify normal operation. If
