Recommended separation
distance:
d = 1,2 √P
d = 1,2 √P 80MHz to 800 MHz
d = 2,3 √P 800MHz to 2,7 GHz
Where P is the maximum
output power rating of the
transmitter in watts (W) ac-
cording to the transmitter ma-
nufacturer and d is the recom-
mended separation distance
in metres (m).
Field strengths from fixed RF

) should be less than
the compliance level in each
frequency range.b
Interference may occur in the
vicinity 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 struc-
tures, 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
Comfort Quick 00000656000000
is used exceeds the applicable RF
compliance level above, the
Comfort Quick 00000656000000
should
be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting
or relocating the
Comfort Quick 00000656000000
