in watts (W) according to the
transmitter manufacturer and d

Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site survey,
a
should be less than the
compliance level in each
frequency range.
b
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 KD-7961N is used
exceeds the applicable RF compliance level above, the KD-7961N should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the KD-7961N.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
