The RadiForce series is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. For other portable 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
• At 80 MHz and 800 MHz, the separation distance for a higher frequency range must be applied.
• These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
