corrupted the information in the equipment memory
circuits. Therefore:

disconnect the plug from the AC line supply
-
after waiting at least three minutes, reconnect
the plug to the AC line supply
-
re-attempt to operate the equipment
Memory backup
• In case a power outage occurs or the power
cord is accidentally unplugged, this unit is
equipped with a backup function to prevent
memory data such as the preset memory
from being erased.

reset the unit with the following procedure.
To turn on the unit, press and hold the SURROUND
MODE and CLEAR buttons simultaneously for 3
seconds or more.
