Guidance and manufacturer’s declaration - electromagnetic emissions
The EQUIPMENT is intended for use in the electromagnetic environment specified below. The
customer or the user of the EQUIPMENT 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
EQUIPMENT, including cables, than
the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
d = [3.5/V1] P
d = [3.5/E1] P 80 MHz to 800 MHz
d = [7/E1] P 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
transmitters, as determined by an
electromagnetic site survey
a
, should
be less than the compliance level in
each frequency range.

Interference may occur in the vicinity
of equipment marked with the
following symbol:
NOTE 1 At 80 MHz 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 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 EQUIPMENT is used exceeds the applicable RF compliance level above, the
EQUIPMENT should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the EQUIPMENT.
