Guidance and Manufacturer’s Declaration –Electromagnetic Immunity
The HoverTech International Air Supply is intended for use in the electromagnetic environment
specified below. The customer or the user of the HoverTech International Air Supply should ensure
that it is used in such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the
HoverTech International Air Supply, including cables,
than the recommended separation distance

Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
a ,
should be less than the compliance level in each
frequency range
b .
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE 1 : At 80 MHZ and 800 MHz, 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.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, and
electromagnetic site survey should be considered. If the measured field strength in the location in which the
device is used exceeds the applicable RF compliance level above, the device should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, the field strengths should be less than 3 V/m.
