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 problem 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.
Factory reset, clearing all memory
1 Press the ON/STAND-BY button to enter the power stand-by
mode.
2 Press and hold TUNING/FOLDER
button on main unit. "RESET" appear.
Caution:
This operation will erase all data stored in memory including clock,
timer setting, tuner preset and CD programme.
Before transporting the unit
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 can damage the unit.
Care of compact discs
Compact discs are fairly resistant to damage, however mistracking
can occur due to an accumulation of dirt on the disc surface. Follow
the guidelines below for maximum enjoyment from your CD
collection and player.
Do not write on either side of the disc, particularly the non-label
side from which signals are read. Do not mark this surface.
Keep your discs away from direct sunlight, heat, and excessive
moisture.
Always hold the CDs by the edges. Fingerprints, dirt, or water on
the CDs can cause noise or mistracking. If a CD is dirty or does
not play properly, clean it with a soft, dry cloth, wiping straight out
from the centre, along the radius.
