While listening to FM broadcasts
An unusual hissing noise is
heard when listening to the
broadcast in stereo, but not
heard when listening
monaurally.
Noise is excessive in both
stereo and monaural broad-
casts.
The FM stereo indicator or
the quartz lock indicator
flickers, without completely
illuminating.
Excessive distortion in the
sound of stereo broadcasts.
A slight noise may be heard because the method
used for modulation of FM stereo broadcasts is
different than that used for monaural broadcasts.
Poor location and/or direction of the antenna.
Transmitting station is too far away.

The incorrect input source has been selected.
The protection circuitry has functioned because
the positive and negative speaker connection
wires have "shorted," speaker systems with an
impedance less than the indicated rated
impedance of this unit have been used or are
under severe use, such as through excessive vol-
ume, excessive power or being in an excessively
hot environment.
• Confirm that the power cord plug is connected
completely.
