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

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

IR REMOTE CONFIGURATION

Resolving IR Code Confl icts

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.
