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 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 the frequency range 150 kHz to 80 MHz, field strengths should be less than [
V
1] V/m.
The device is intended for use in the electromagnetic environment specified below. The
customer or the user of the device should assure that it is used in such an environment.
Portable and mobile RF
communications equipment should
be used no closer to any part of the
device, including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the

Recommended separation distances between
portable and mobile RF communications equipment and the device
The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the device can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the device as recommended
below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in
metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where
P
is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 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
