Memory backup

•In case a power outage occurs or the power cord is accidentally unplugged, the SR6400 is equipped with a backup function to prevent memory data such as the preset memory from being erased.

Should the operation or display seem to be abnormal, reset the unit with the following procedure.

The SR6400 is turned on, press and hold the SELECT and ATT buttons simultaneously for 3 seconds or more.

Remember that the procedure will reset the settings of the function selector, Surround mode, delay time, TUNER PRESET etc., to their initial settings.
