ELECTROMAGNETIC COMPATIBILITY (EMC)
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.

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.
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.

Recommended separation distances between
portable and mobile RF communications equipment and device
The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of device can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and device, as recommended below, according to the maximum output
power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can
be estimated using 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
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
