!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:

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

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

When the protection circuit is activated:

When short-circuiting the speaker leads or turning the volume too high, the protection circuit may be activated and the system may enter the stand-by mode.

Unplug the unit and, after 15 minutes or more, plug it in again. Turn down the volume if set too high.

!Before transporting the unit

1Press the ON/STAND-BY button to turn the power on.

2Press the OPEN/CLOSE button to open the disc tray.

Remove the disc inserted in the unit.

3Press the OPEN/CLOSE button to close the disc tray.

4Press the ON/STAND-BY button to enter the stand-by mode, and then unplug the AC power lead from the wall socket.

!Condensation

Sudden temperature changes, storage or operation in an extremely humid environ- ment may cause condensation inside the cabinet (laser pickup, etc.) or on the trans- mitter on the remote control.

Condensation can cause the unit to malfunction. If this happens, leave the power on with no disc in the unit until normal playback is possible (about 1 hour). Wipe off any condensation on the transmitter with a soft cloth before operating the unit.
