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:

The RadiForce series is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. For other por-
table and mobile RF communication equipments (transmitters), minimum distance between portable and mobile RF communications equipment
(transmitters) and the RadiForce series 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 separation distance for a 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.
