Immunity Test IEC 60601
Test level
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, ob-
jects 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 theoreti-
cally with accuracy. To assess the electromagnetic environment due to
fixed RF transmitters, an electromagnetic site survey should be consid-
ered. 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 neces-
sary, 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.
