Guidance and manufacturer’s declaration – electromagnetic immunity
The GL5.2 is intended for use in the electromagnetic environment specied below.
The customer or the user of the GL5.2 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 GL5.2, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation
distance
d=1,2√Pd=1,2√P 80 MHz to 800 MHz
d=2,3√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 recom-
mended separation distance in meters (m).
Field strengths from xed 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 equip-
ment 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 a󰀨ected by
absorption and reection from structures, objects and people.
a)
Field strengths from xed 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 xed RF transmitters, an
electromagnetic site survey should be considered. If the measured eld strength in the location in which
the GL5.2 is used exceeds the applicable RF compliance level above, the GL5.2 should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the GL5.2.
b)
Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
