Guidance and manufacture's declaration-electromagnetic immunity
The device is intended for use in the environment specified below. Buyer or operator should
assure that it is used in such environment.

NOTE 1: At 80MHz 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 or system 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 adjusting the direction or location of the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance
Electromagnetic environment -guidance
level
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
3 Vrms
d=1.2√P
d=1.2√P 80MHz-800MHz
d=2.3√P 800MHz-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
