5. Button Control
5.1 Source Switching
1) Press the SOURCE AUTO button to switch to next source device, and then the
corresponding input LED will turn green.
2) Press and hold the SOURCE AUTO button at least 3 seconds to enable auto
switching mode, and it abides by the following principles:
⚫New Input
Once detecting a new input signal, the switcher will automatically switch to this
new signal, and the far-end display device will receive command to be switched
on. If source input is not detected, the far-end display device will automatically
turn off within two minutes.
⚫Source Removed
When an active source is removed, the switcher will switch to the first available
active input starting at HDMI IN 1.
⚫Reboot
The switcher can save the last configuration before losing power. If the last
switching mode is auto switching, the switcher will automatically enter auto
switching mode once rebooted, then detect all inputs and memorize their
connection status for future rebooting using. If the last selected input source is
still available, the switcher will switch to this input. If not, it will switch to the first
available active input source starting at HDMI IN 1.
⚫Exit auto switching mode
Press and hold the SOURCE (AUTO) button for 3 seconds again to exit the auto
mode, and the input source will not be changed.
