Field strengths from

less than the com-

.
Note 1:
At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2:
These guidelines may not apply in all situations. Electromagne-
tic propagation is affected by absorption and reflection from
structures, 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
MEDIC Vaporizer is used exceeds the applicable RF compliance
level above, the MEDIC Vaporizer should be observed to verify
normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the
MEDIC Vaporizer.
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3 V/m.
