This device is intended for use in the electromagnetic environment specified below. The user of
this device should make sure it is used in such an environment.

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, the field strengths should be less than 3 V/m.

3 A/m Power frequency magnetic fields should be
at levels characteristic of a typical location in a
typical hospital or home 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 transmitter.

d = 1.2
d = 1.2

3 V/m
where P is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-
mended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
should be less than the compliance level in
each frequency range.
