Possible cause
Possible cause
" Condensation
Sudden temperature changes, storage or operation in an extremely
humid environment may cause condensation inside the cabinet
(laser pickup, etc.) or on the transmitter on the remote control.
Condensation may cause the system to malfunction. If this hap-
pens, leave the power on with no disc in the system until normal
playback is possible (about 1 hour). Wipe off any condensation on
the transmitter with a soft cloth before operating the system.
" 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 system to the stand-by mode and turn the power on
again.
2 If the system is not restored in the previous operation, unplug and
plug in the subwoofer/amplifier unit, and then turn the power on.
Note:
If neither operation above restores the system, 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 While pressing down the button and the FUNCTION button,
press the ON/STAND-BY button until "SYS RESTORE" appears.
Caution:
When you reset, all data is deleted and the settings return to the
default. (DVD initial settings are retained.)
