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 enssure 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 that
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 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: At 80MHz and 800MHz, 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
mobiles 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 verity 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.
