IR REMOTE INSTALLATION

Installing the IR Remote Control Battery

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.

It is important that the IR channel selected on the remote, match the IR channel on the GefenTV 4×1 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 4×1 Switcher for HDMI 1.3 to use IR channel 0.

See page 9 for information on how to change the IR channel on the GefenTV 4×1 Switcher for HDMI 1.3.

CHANGING THEIR CHANNEL

Setting The IR Channel

Use the following procedure to set the proper IR channel on the Switcher.

1. Press and hold the EQ button for approximately 5 seconds to enter the IR channel selection mode. The currently selected IR channel will by indicated by a fl ashing blue LED on the Input Indicators (page 5).
