5. Button Control
5.1 Manual Switching
When the switcher is in the manual switching mode, the Auto Mode LED goes out. If
need to change the input source, please directly press the 1, 2, 3, 4, 5 or 6 button, and
the corresponding LED illuminates green immediately.
5.2 Automatic Switching
Press and hold the AUTO button at least three seconds to enable automatic switching,
and the Auto mode LED will light.
When in the Auto mode, the switcher will switch according to the following rules:
 The switcher will switch to the first available active input starting at input 1 to 6.
 New input: The switcher will automatically select the new input once detecting a new
input.
 Reboot: If power is restored to the switcher, it will automatically reconnect the input
before powered off.
 Source removed: When an active source is removed, the switcher will switch to the
first available active input starting at 1-HDMI/MHL input.
 Press the Video Source button (1, 2, 3, 4, 5 or 6) can directly change the input
source. If the corresponding source device is active, it will be switched as input
source; otherwise, the switcher will switch to the first available active input starting at
1-HDMI/MHL input.
 Press and hold the AUTO button at least three seconds again can exit AUTO mode,
but the input source will remain the current setting.
5.3 Display Control
The switcher supports CEC, and the DISPLAY CONTROL buttons on the front panel
are designed for Display On/Off and volume adjustment.
 ON: Display On.
 OFF: Display Off.
 : Mute/unmute display audio.
 : Volume down display audio.
 : Volume up display audio.

5.4 VGA Resolution Selection
The RES button on the front panel is designed for VGA resolution selection.
OFF: Display Off.
Press RES button repeatedly to set the VGA resolution to 1280x720, 1920x1080 or
1920x1200, and its corresponding LED will illuminates green.
5.5 EDID Setting
The Extended Display Identification Data (EDID) is used for the source device to match
its video resolution with the connected display. By default, the source device obtains its
EDID from the first connected display. Meanwhile, since the displays with different
capabilities are connected to the switcher, the 4-pin DIP switch on the rear panel can be
used to set the EDID to a built-in fixed value. Use the following table to determine the
setting for the 4-pin DIP switch for specific video resolution and audio capabilities.
The switch represents “0” when in the lower (OFF) position, and it represents “1” while
putting the switch in the upper (ON) position.
