Troubleshooting chart (continued)
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.
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 again, and then turn the
power on.
Note:
If neither operation above restores the unit, clear all the
memory by resetting it.
Caution:
This operation will erase all data stored in memory
including clock, timer settings and tuner preset.
If the Network function operates incorrectly, do the reset
operation as below:
During Network function, press and hold CLEAR button
until “Network Clear” appears.
This operation will erase the current Wi-Fi setting.
