Recommended separation distances between portable or mobile RF communication equipment
and the RadiForce Series
The RadiForce series is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the RadiForce series can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the
RadiForce series.
Immunity to proximity fields from following RF wireless communication equipments has been confirmed:
