equipment should be
used no closer to any
part of the PS24FHDCR,
including cables, than
the recommended
separation distance
calculated from the
equation applicable
to the frequency
of the transmitter.
Recommended
separation distance
d = 1.2 √ P
d = 1.2 √ P 80 MHz to 800
MHz
d = 2.3 √ P 800 MHz to 2.5
Ghz
Where P is the maximum
output power rating
of the transmitter in
watts (W) according
to the transmitter
manufacturer and d
is the recommended
separation distance in
meters (m).
Field strengths from
fi xed RF transmitters,
as determined by an
electromagnetic site
survey,

should be less
than the compliance
level in each frequency
range.

Interference may occur in
the vicinity of equipment
marked with symbol:
At 80 MHz and 800 MHz, the higher frequency range applies.
3. The PS24FHDCR has been tested at 10 V/m
4. 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 PS24FHDCR is used exceeds the applicable RF compliance level above, the PS24FHDCR should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the PS24FHDCR.
5. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
