Electromagnetic Compatibility Declaration
Table 9. Guidance and manufacturer’s declaration – electromagnetic emissions
The EPG is intended for use in the electromagnetic environment specified below. The customer or the user
of the EPG 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 EPG, including cables,
than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance
Not applicable – Battery powered device
d=1.2 80 MHz to 800 MHz
d= 2.3 800 MHz to 2.5 GHz
where P is the maximum output 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.
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
EPG is used exceeds the applicable RF compliance level above, the EPG should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting
or relocating the EPG.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
