Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
This equipment is intended for use in the electromagnetic environment specified below. The customer or the end user of this
equipment
should assure it is used in such an environment.

Portable and mobile RF communications equipment should be
used no closer to any part of this equipment, including cables,
than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.2√P
d = 1.2√P 80MHz to 800 MHz
d = 2.3√P 800MHz to 2.5GHz
where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended minimum separation
distance in meters (m).
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).

NOTE 1:
At 80MHz and 800MHz, the higher frequency range applies.
NOTE 2:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from objects, structures
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 this equipment is used
exceeds the applicable RF compliance level above, this equipment should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating this equipment.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
