Condensation
Sudden temperature changes, storage or operation in an extremely
humid environment may cause condensation inside the cabinet (CD
pickup, 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 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.
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 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.
Clearing all the memory (reset)
1 Press the ON/STAND-BY button to enter the power stand-by
mode.
2 Whilst pressing down the 1 button and the 5 button, press
the ON/STAND-BY button until "CLEAR ALL" appears.
Caution:
This operation will erase all data stored in memory including clock,
timer settings, tuner preset, and CD programme.
