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

Portable and mobile RF communications
equipment should be used no closer to any
part of the system, including cables, than the
recommended
separation
distance
calculated from the equation appropriate for
the frequency of the transmitter.
Recommended separation distances:
P

80 MHz - 800 MHz
P

3
.
2
800 MHz - 2.5 GHz
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
can occur in the vicinity of equipment
marked with the following symbol:
.
Note 1: At 80 MHz to 800 MHz, the separation distance for the higher frequency range applies.
Note 2: These guidelines can 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 can be necessary, such
as reorienting or relocating the device.
b. Field strengths should be less than 3 V/m between 150 kHz and 80 MHz.
