■
Remote control
Symptom
● The remote control does not op-
erate.
Possible cause
● Is the AC power cord of the unit plugged
in?
● Is the battery polarity respected?
● Are the batteries dead?
● Is the distance or angle incorrect?
● Does the remote control sensor receive
strong light?
■
Condensation
Sudden temperature changes, storage or operation in an extremely humid envi-
ronment 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 unit.
■
Connecting DVD player
Symptom
● Although a DVD player is con-
nected, no sound is heard.
Possible cause
● Is the power to the DVD player con-
nected properly?
● Is a digital signal being output from the
DVD player?
● Is “DVD NO” being displayed?
● Does the type of DVD digital signal ap-
pear in the display?
● Since “DVD---” is not output from the
Dolby digital source, it cannot be
decorded. (Refer to page 28.)
● Is a Dolby digital 2/0 (monaural) signal
being played with the surround mode set
to NORMAL and without a center
speaker connected?
■ If trouble occurs
When this product is subjected to strong external interference (mechanical shock, ex-
cessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is oper-
ated 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.
