Troubleshooting Guide
What might appear to be a malfunction in your unit may just be the result of slight misoperation or miswiring. Before
calling service, first check the following table for possible problems.
SOLUTIONPOSSIBLE CAUSEPROBLEM
The fader and/or balance settings are set all the way to
one side.
Reset the fader and/or balance settings.
The input/output cables or wiring harness are connected
incorrectly.
Connect the input/output cable or wiring harness correctly.
See "Connections".
Nothing happens when the
buttons are pressed.
The computer chip in the unit is not functioning normally. Press the reset button on the unit (see page 3).
The power is not turned on. The fuse has blown. After checking for short circuits in the cables, replace the
fuse with one having the same rating.
The power control cable are connected incorrectly. Connect the same cable to the centre unit.
No sound can be heard, or the
volume is low.
The front or rear speaker does
not output sound.
The fader is set to one side. Adjust the fader.
The 16kHz indicator of the
spectrum analyzer does not
light.
In particular, the indicator may not light for a cassette
tape because the 16kHz level of the source is low.
If it lights when you play a compact disc, there is no
problem.
Hiss noise is generated. The graphic equalizer level is too high. Set the graphic equalizer level to a correct level.
The main unit panel is open. Close the panel.
The power amp input sensitivity setting is wrong. If the front and rear level gain is set to "HIGH", set the power
amp input sensitivity to 4V.
The sound is distorted. The main unit input sensitivity setting is wrong. Match the main unit input sensitivity setting to the output
voltage of the centre unit (see page 7).
