Guidance and manufacturer’s declaration – electromagnetic immunity
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 transmitter.

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 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 3V/m.
