Setting the auto standby function

AUTO STANDBY switch
When the AUTO STANDBY switch is set to ON, the amplifier switches
to standby mode automatically when the output level from the
speaker or headphones has been lower than a certain level for about
10 to 15 minutes (Auto standby function). Therefore, if you listen to
music at a low volume for a while, the auto standby function may be
activated. In this case, set the AUTO STANDBY switch to OFF.
The output level at which the auto standby function is activated, or the
time when the amplifier switches to standby mode differs, depending
on the conditions under which you are using the amplifier.
