• Adjust the antenna.
• Press DIGITAL INPUT/ST/MONO button to insure
you are not outputting in mono.
The signal is Mono. Severe hum or noise.
• The signal is too weak. Connect an external anten-
na.

• Reposition Antenna away from any electronics.
Remote Control Operation
The remote control does not operate the unit.
• Another source mode is selected on the remote.
Press the correct Source Button.
• No batteries installed. (included with your system)
Install the batteries before attempting to operate the
remote. Be sure to match the + and - ends of each
battery to the symbols shown in the remote battery
compartment.
• The batteries are weak. Replace all batteries.
• The remote is not pointed at the remote control
sensor on the main unit or there is an obstacle
between the remote and the main unit.
• The remote control is too far from the main unit,
move closer.
General
No audio.
• Make sure the speakers are connected.
• Check the input connections.
• Check the power cord connections.
• Make sure the MUTE signal on the front panel is
off.
• Make sure the digital setting (optical, coaxial or
analog) is correct.
• Check that the headphone is not inserted.
No audio from one channel.
• Check the speaker level setting.
• Check the speaker wire or external source cable
connections.
Noise occurs when the TV is turned on.

inserted.
Cleaning the Exterior
• Disconnect the system from AC power before clean-
ing the exterior of the system with a soft dust cloth,
or with a slightly damp leather chamois. Never use
strong solvents.
