Portable and mobile RF communications
equipment should be used no closer to any
part of the system, including cables, than

the frequency of the transmitter.

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 to 800 MHz, the separation distance for 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 device is used
exceeds the applicable RF compliance level above, the device should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the device.
b
Over frequency range 150kHz to 80MHz. For Resp field strength should be less than
1V/m.
