a:
Field strength from fixed transmitters, such as base stations for radio (cellular/
cordless) telephones and land mobile radios, amateur radio, AM and FM radio
stations and TV stations 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 device is used exceeds the applicable RF compliance level above, the
device should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating
the device.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than

Technical information
Electromagnetic environment -
guidance
Portable and mobile RF radio
equipment should be used no
closer to any part of the device,
including cables, than the rec-
ommended separation distance
calculated from the equation
applicable to the frequency of
the transmitter.
Recommended separation
distance:
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 metres (m).
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site survey
, should be less than the com-

Recommended separation distances between portable and mobile RF communica-
tions equipment and the device.
The device is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the device can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the device as
recommended below, according to the maximum output power of the communica-
tions equipment.

For transmitters rated at a maximum output power not listed above, the recom-
mended separation distance d in metres (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.
