recommended separation distances

The AIR-FLOW MASTER is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
the AIR-FLOW MASTER can help to prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the AIR-FLOW MASTER 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 metres (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 trans-
mitter 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.
