Troubleshooting Chart (continued)

■If trouble occurs

When this product is subjected to strong external interference (mechanical shock, excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction.

If such a problem occurs, do the following:

1.Set the unit to the stand-by mode and turn the power on again.

2.If the unit is not restored in step 1, unplug and plug in the unit, and then turn the power on.

Note:

If neither operation above restores the unit, clear all the memory by resetting it.

■Clearing all the memory (reset)

1.Press the ON/STAND-BY button to enter the power stand-by mode.

2.Whilst pressing down the PRESET W button and the DISPLAY (DEMO) button, press the ON/STAND-BY button.

After the “RESET” is displayed for about 1 second, the unit will enter the power stand-by mode.

Caution:

This operation will erase all data stored in memory including clock, timer settings, tuner preset, and CD or MiniDisc programme.

■Before transporting the unit

Remove the CD and the MiniDisc from the unit. Your unit checks whether there is a disc inside the unit when the compartment is closed. “NO DISC” appears if no disc is left. Then, set the unit to the power stand-by mode. Carrying the unit with discs left inside can damage it.

Maintenance

■Cleaning the CD pickup lens

Do not touch the laser pickup lens. If fingerprints or dust accumulate on the pickup, clean it gently with a dry cotton swab.

■Cleaning the cabinet

Periodically wipe the cabinet with a soft cloth and a diluted soap solution, then with a dry cloth.

Caution:

●Do not use chemicals for cleaning (petrol, paint thinner, etc.). It may damage the cabinet finish.

●Do not apply oil to the inside of the unit. It may cause malfunctions.
