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 AC-300MD is used exceeds the applicable RF compliance level above, the AC-
300MD should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the AC-300MD.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
c The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to
6.

Recommended separation distances between portable and m
obile RF communications equipment
and the AC-300MD
The AC-300MD is intended for use in an electromagnetic environment in which radiated RF disturbances
ar
e contro
lled. The customer or the user of the AC-300MD can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the AC-300MD as recommended below, according to the maximum output power of
the communications equipment.

For transmitters rated a maximum output power not listed a
bove, the recommended separation
distance
d
in meters (m) can be estimated using the equation applicable to the frequency of the
transmitter, where
P
is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorpti
on and reflection from structures, objects and people.
