Portable and mobile RF communications
equipment should be used no closer to
any part of the CF-1, including cables,
than the recommended separation dis-
tance calculated from the equation appli-
cable to the frequency of the transmitter.
Recommended separations distance
where P is the maximum output power rat-
ing of the transmitter in watts (W) accord-
ing to the transmitter manufacturer and d
is the recommended separation distance
in meters (m).

Interference may occur in the vicinity of
equipment marked with the following sym-
bol:
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 reflections from structures, objects and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) tele-
phones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast can-
not 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 where the CF-1 is used exceeds the applicable RF compliance level above,
the CF-1 should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the CF-1.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
