Guidance and manufacturer's declaration - electromagnetic immunity
The device is intended for use in the electromagnetic environment specified below. The
user of the device should make sure 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 transmitter.
Recommended separation
distance
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
transmitter, 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 applied.
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 10
V/m.
