General

the system" on page 8).
• Press DISPLAY twice when the system is turned
off. The demonstration disappears.
"– –:– –" appears in the display.

• The power cord is disconnected or a power
failure occurs longer than half a day.
Redo the following:

the display when you press 5.1CH/VIDEO (MD)

persists, place the speakers farther away from the
TV set.
Speakers

left and right volume.

each set of speaker terminals.
