Widex TV-DEX - Recommended Separation Distances

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 TV-DEX is used exceeds the applicable RF compliance level
above, the TV-DEX 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 TV-DEX.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.
