Guidance and manufacturer's declaration – electromagnetic immunity
The GCE834 is intended for use in the electromagnetic environment specified below.
The customer or the user of the GCE834 should assure that it is used in such an environment.

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 struc-
tures, 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
GCE834 is used exceeds the applicable RF compliance level above, the GCE834 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the GCE834.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communications equipment and the GCE834
The GCE834 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user
of the GCE834 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF commu-
nications equipment (transmitters) and the GCE834 as recommended below, according to the maximum output power of the communications
equipment.
