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 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 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 3V/m.
Recommended separation distances between portable and mobile RF
communications 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 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.
