The GefenTV Switcher

Hi-Def sources to one HDTV display. Resolutions up to 1080p Full HD with
multichannel digital audio are supported. 3D content can be displayed when
connecting a 3DTV and 3D source. The front panel LEDs show the currently
selected source. This 4x1 Switcher has an auto-switching feature: If a new
source is connected or turned on, the Switcher will automatically switch to that
input. The 4x1 Switcher will revert to the previous input once the current device
is turned off or disconnected. Any of the four Hi-Def sources can be selected by
the push-button, IR remote control, or using the RS-232 control.

IR REMOTE INSTALLATION
Resolving IR Code Conflicts
In the event that IR commands from other remote controls confl ict with the
supplied IR remote control unit, changing the remote channel will alleviate
this issue. The IR remote control unit has a bank of DIP switches for setting
the remote IR channel.
The DIP Switch bank on the IR remote control unit is located underneath
the battery cover.
DIP Switches
It is important that the IR channel selected on the remote, match the IR channel
on the GefenTV 4x1 Switcher for HDMI 1.3 for proper operation. For example, if
you set both DIP switches on the remote to the down position (toward the “1” and
“2”), IR channel 0, you must set the GefenTV 4x1 Switcher for HDMI 1.3 to use
IR channel 0.
