Recommended separation distances between portable and mobile RF communications equipment and the Varios 970 / Varios 970 LUX.
The Varios 970 / Varios 970 LUX is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
the Varios 970 / Varios 970 LUX can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Varios 970 / Varios 970 LUX 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 the 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.
