For HT-SL77
Sudden temperature changes, storage or operation in an
extremely humid environment may cause condensation
inside the cabinet. Condensation can cause the unit to
malfunction. If this happens, leave the power on until
normal playback is possible (about 1 hour).
When this product is subject 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 the unit is not restored in the previous operation,
unplug and plug in the unit again
or
unplug all component connected and plug in again.
During the Amplifier power on position (BLUE indicator
light up), press the PAIRING button for more than 10
seconds.
Note:
This operation will restore the DIGITAL (HDMI) function
volume to the default setting.
Periodically wipe the cabinet with a soft cloth.
Caution:
• Do not use chemicals for cleaning (gasoline, paint
thinner, etc.). It may damage the cabinet finish.
• Do not apply oil to the inside of each component. It may
cause malfunctions.
