Canceling muting
• The time required to cancel muting varies depending on the acoustic-field setting.
It takes longer to cancel muting if SFC or the channel level has been set.
• When the function is set to DVD, the time required to cancel muting differs depending
on a DVD operation. Muting continues until disc detection has been finished.
