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