Guidance and manufacturer’s declaration — electromagnetic immunity
The equipment is intended for use in the electromagnetic environment specified below. The customer or
the user of the equipment should assure that it is used in such an environment.
Immunity test

Electromagnetic environment –
guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the equipment, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

Interference may occur in the vicinity of
equipment marked with the following
symbol:
Recommended separation distances to portable and mobile RF communication equipment
The equipment is intended to be operated in an electromagnetic environment, where radiated RF
interference is controlled. The user can help in avoiding interferences by means of meeting minimum
separation distances between portable and mobile RF communication equipment (transmitters) according
to the maximum output power of the communication equipment.
