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 structures, 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 broad-
cast 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
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 re-orienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than

Recommended separation distances between portable and mobile RF
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
(transmittters) and the device as recommended below, according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
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. NOTE 1 At 80MHz
and 800MHz, the separation distance for the higher frequency range applies. NOTE 2
