Interference may

occur in the vicin-

ity of equipment

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 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.
