Immunity Test
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 COM-DEX Remote Mic
is used exceeds the applicable RF compliance level above, the COM-DEX
Remote Mic should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
re-orienting or re-locating the COM-DEX Remote Mic.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3 V/m.
Recommended separation distances
Recommended separation distances between portable and mobile RF
communication equipment and the COM-DEX Remote Mic.
The COM-DEX Remote Mic is intended for use in the electromagnetic
environment in which RF disturbances are controlled. The customer or the
user of the COM-DEX Remote Mic can help prevent electromagnetic
interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the COM-DEX
Remote Mic as recommended below, according to the maximum output
power of the communications equipment.
