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

including cables than the recommended separation

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 Corti
is used exceeds the applicable RF compliance level above, the Corti should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the Corti.
(b*) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
