Condensation
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 CLOCK button and the EQUALIZER/X-BASS/DEMO
button, press the ON/STAND-BY button until "CLEAR AL" appears.

Sudden temperature changes, storage or operation in an extremely humid environ-
ment 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

Maintenance
Cleaning the tape-handling parts
Dirty heads, capstans or pinch rollers can cause poor sound and tape jams. Clean
these parts with a cotton swab moistened with commercial head/pinch roller
cleaner or isopropyl alcohol.
When cleaning the heads, pinch rollers, etc., unplug the unit which contains high
voltages.
After long use, the deck's heads and capstans may become magnetised, causing
poor sound. Demagnetise these parts once every 30 hours of playing/recording
time by using a commercial tape head demagnetiser. Read the demagnetiser's
instructions carefully before use.
