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.

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 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 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 maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the device as recommended
below, according to the maximum output power of the communications equipment.
