Declaration - electromagnetic immunity
The device is intended for use in the electromagnetic environment specified below.
The customer or the user of 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 device, than the recommended separation
distance calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance:
d = 1.2√P 150 kHz to 80 MHz
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz to 2.7 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,
should
a
be less than the compliance level in each
frequency range.
Interference may occur in the vicinity of equipment
marked with the following symbol:

Field strengths from fixed RF 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 device is used exceeds the applicable RF compliance
level above, device should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
re-orienting or relocating device. Over the frequency range 0.15 MHz to 80 MHz,
field strengths should be less than 3 V/m.
