4. System Control
4.1 Input Switching
The button “SOURCE/MODE/3s” on the front panel can be used to select input and
switch mode.
4.1.1 Manual switching mode
Press “SOURCE/MODE/3s” button to toggle between input 1~4, the corresponding
indicator illuminates green for easy identification.
4.1.2 Auto switching mode
Press and hold the button “SOURCE/MODE/3s” for 3 seconds or more to switch
between the manual and auto modes. (Default: Manual mode.). Once you enter auto
switch mode, the “AUTO” LED will light up.
The auto switch mode abides by the following principles:
New input
Once it detects a new input signal, the switcher will switch to this new signal
automatically.
Power Rebooting
The switcher has a power off memory function. If the last selected signal is
still available, the switcher will still output the signal. If not, the switcher will
detect all the input signals with priority from “IN 1” to “IN 4” ports. The next
available signal will be transferred to the output.
Source removal
Removing the current input signal, the switcher will detect all the input signals
connected. The next available signal will be transferred to the output.
For example, the selected input signal is “IN 2”, if you disconnect the current
input source, the AVG-UHMS41-V2 will transfer the next available signal to
the output. It will choose this source according to the following order: “IN 3”,
“IN 4”, “IN 1” and so on, until it finds a signal.

4.2 Embedded EDID invoking
The rear panel boasts a 4-pin DIP switch to invoke an embedded EDID. The
embedded EDID data and its corresponding DIP switch status are shown in the
