Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The GSI AudioStar Pro is intended for use in the electromagnetic environment specified below. The customer or the
user of the AudioStar Pro should assure that it is used in such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the
AudioStar Pro, including cables than the
recommended separation distance calculated from
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 and
d
is the recommended separation
distance in meters (m).
Field Strengthens 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:
Note 1:
At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2
: These guidelines may not apply to 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, an electromagnetic site survey
should be considered. If the measured field strength in the location in which the AudioStar Pro is used exceeds the
applicable RF compliance level above, the AudioStar Pro should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
AudioStar Pro.
(b*) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
