Auto power-off function

The amp has an auto power-off function. With this function, the amp is
automatically turned off if there is no operation or input for approximately
1 hour. When the amp is turned off, it is not turned back on, even if a knob
or selector is operated. After the amp is turned off, turn it on again.
When the input level is extremely low or there is very little change in
the sound, the auto power-off function may be activated. In addition,
depending on the settings and environment, the amp may interpret
noise as input, even if the guitar is not being played.
The auto power-off function will not operate while the amp is
connected using a USB cable.
As the factory default setting, the auto power-off function is enabled.
