Sound is produced from one
speaker only.
Noise is produced during recep-
tion of AM broadcasts when the

High noise level.
Remote control does not work.
Cause
• Power cord is disconnected.
. VOLUME control is set to MIN.
• Speaker connecting wires are disconnected
from speaker terminals.
• One or both of the input cords are disconnect-
ed.

tion.
• Speakers buttons are in the OFF position.
• BALANCE control is set too far to one side or
the other.
• One of the speaker connecting wires or input
cords is disconnected.
• AM loop antenna picks up electrical noise
created by switch contacts.
• Station has not been tuned in to correct fre-
quency.
• Antenna has not been connected or has
become disconnected.
FM reception
• Accessory FM antenna remains bundled up.
• Weak broadcasting station signals.
• Noise picked up from other equipment (or, in
particular, from passing automobiles).
• Multipath results when signals from broadcast-
ing station entering antenna directly are mixed
with signals which have been reflected by
mountains or high buildings on their way to an-
tenna, this results in distorted sound and
noise.
AM reception
• AM antenna not pointing in right direction.
• Weak broadcasting station signals.
• Noise being picked up from other equipment
(especially electrical appliances using motor or
fluorescent lights).
• Batteries are dead or no batteries in remote
control unit.
• Poor angle or too great a distance from the re-
mote sensor window.
• There is an obstacle between you and the re-
mote sensor window.
• For CD player and cassette decks, the remote
control cord is not connected.
• A fluorescent light is shining on the remote
sensor window.
Remedy
• Connect cord securely.
• Turn the VOLUME control toward the right.
• Connect wires to terminals securely.
• Connect input cords securely.
• Press the button to OFF position.
• Press the button to ON position.
• Set BALANCE control to center position.
• Connect wires and cords securely.
Place AM loop antenna as far away as possible
from this and other components.
• Tune the station correctly.
• Connect the antenna securely.
Stretch the antenna taut and locate in direc-
tion yielding optimum reception.
Replace accessory FM antenna with outdoor
FM antenna.
Try altering direction and mounting position of
antenna. If an outdoor antenna has been erect-
ed, place it as far as possible from passing
traffic and replace connecting cable with 75
coaxial cable.
• Change AM antenna's direction and find a posi-
tion where reception is improved,
• Erect outdoor AM antenna or connect ground
wire.
• Stop using appliances generating noise or re-
move them from vicinity of stereo equipment.
• Insert new batteries.
• Use within 7 meters (23 feet) and within a 30
degree angle of the remote sensor window.
• Change your position or move the obstacle.
• Correctly connect remote control cord.
• Turn off the light.
Abnormal functioning of this unit may be caused by lightning, static electricity, or other external interference. To restore normal operation,
