Guidance and manufacturer's declaration – electromagnetic immunity
The device is intended 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.

NOTE 1 At 80 MHz 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 predicated 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 range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment - guidance
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
d = 1.2 P
d = 1.2 P
80 MHz to 800 MHz
d = 2.3 P
800 MHz to 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 recom-
mended separation distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site
a
survey
, should be less than the compliance
level in each frequency range
