equipment should be used no closer to any
part of the KD-927, including cables, than
the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
：
80 MHz to 800 MHz
800 MHz to 2,5 GHz
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 meters (m).

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.

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
