If trouble occurs
H
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 the previous operation, 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.
Before transporting the unit
H
Remove all CDs from the unit. Make sure there is no CD in the disc tray. Then,
set the unit to the power stand-by mode. Carrying the unit with discs left inside

Caution:
This operation will erase all data stored in memory including clock, timer settings,

Condensation
H
Sudden temperature changes, storage or operation in an extremely humid
environment may cause condensation inside the cabinet (CD pickup, tape heads,
etc.) or on the transmitter on the remote control.
Condensation can cause the unit to malfunction. If this happens, leave the
power on with no disc (or cassette) 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.
