Portable and mobile RF communications
equipment should be used no closer to
any part of the [KD-5905], 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).
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-5905] is used exceeds the
applicable RF compliance level above, the [KD-5905] 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-5905].
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
