abnormal, while the channel
2 is normal, it will automatic
switch to the channel 2.
Triggering: the automatic
switch mode is set. The

the input port 2 is remained
normal.
Reason: the output source
is in the automatic mode.
When the channels 1 and 2
are abnormal, while the
channel 3 is normal, it will
automatic switch to the
channel 3.
Triggering: the automatic
