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, should be observed to verify
normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the
device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should
be less than [Vi] V/m.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in meters (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) accordable to the
transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz. the separation distance for the higher
frequency range applies.

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 as recommended
below, according to the maximum output power of the communications
equipment.
