be used no closer to any part of
the sound processor, including
cables, than the recommended
separation distance calculated
from the equation applicable to
the frequency of the transmitter.
*Essential performance of the Chorus Sound Processor per
IEC 60601 is defined as auditory stimulation within safe
amplitudes.
RF interference may occur in the vicinity of equipment marked
with the
symbol.
The Chorus Sound Processor is intended for use in electro-
magnetic evironments with controlled RF disturbances. Elec-
tromagnetic interference may be prevented by maintaining
distance between portable or mobile RF transmitters and the
Chorus Sound Processor, as recommended.
