Auto Power On/Off Function
When powered on, if no input signal is received after 5–10 minutes,
the power is switched off automatically. When an input signal is
received, the power is switched back on automatically. This
function works only when the power switch is in the on position.
Note: The power may switch off automatically when the input signal
level is very low. If this does occur, increase the output level from the
source device and reduce the YST-SW20 VOLUME control accordingly.
