Guidance and Declaration - Electromagnetic Immunity
The device is suitable for use in the electromagnetic environment specified below. The customer
or the user of the device should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the device, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter. Recommended separation
distance:
Pd 2.1=
Pd 2.1=
80M to 800MHz
Pd 3.2=
800M to 2.5GHz
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).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in
each frequency range
b
Interference may
occur in the vicinity of equipment marked
with the following symbol:
.
Note 1: From 80 MHz to 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 reorienting or relocating the device.
b: Over the frequency ranges 150kHz to 80MHz, field strengths should be less than 3V/m.
