6 Vrms Portable and mobile RF
communications equipment
should be used no closer to any
part of the devices, including
cables, than the recommended
separation distance calculated
from 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 and d
is the recommended separation
distance in meters (m).

Guidance and Manufacturer’s Declaration: Electromagnetic Immunity
The devices are intended for use in the electromagnetic environment specifi ed below. The customer
or user of the devices should ensure that they are used in such an environment.
(a) Field strengths from fi xed 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 fi xed RF transmitters, an electromagnetic site survey should be considered. If the measured
fi eld strength in the location in which the devices are used exceeds the applicable RF compliance
level above, the devices should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the devices.
(b) Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.
