Guidance and manufacturer’s declaration–electromagnetic immunity
The Eclipse 3 is intended for use in the electromagnetic environment specied below. The customer or the user of the Eclipse 3
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 Eclipse 3, including cables, than
the recommended separation distance cal-
culated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
80 MHz to 800 MHz
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 metres
(m).
Field strengths from xed RF transmitters, as
determined by an electromagnetic site sur-
vey,
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 sym-
bol:
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 aected by absorption and reection
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 Eclipse 3 is used exceeds the applicable RF compliance level above, the
Eclipse 3 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Eclipse 3.
b
Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
