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.

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.

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 be less than the
compliance level in each frequency range. Interference
may occur in the vicinity of equipment marked with the
following symbol:
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.
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 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.

Recommended separation distances between portable and mobile RF communications equipment and the
device
The device is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the device can help prevent electromagnetic interference by
