RMT2-IR Installation

1. Remove battery cover from the back of the RMT2-IR remote.

2. Verify that dip switches 1 & 2 are in the down (OFF) position.

3. Insert the battery, hold the battery so that you can see the positive side facing up. The
side that is not marked must be facing down.

4. Test the RMT2-IR remote by pressing ONLY one button at a time. The indicator light
on the remote will fl ash once each time you press a button. WARNING: Do not press
multiple buttons simultaneously and do NOT press buttons rapidly. These actions will
cause the remote to reset and steps 1-4 will have to be repeated.

Note: The RMT2-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.

The optional IR extender allows you to re­locate your HDTV switcher and still have IR
control of the HDTV Switcher

IR Code Confl icts

How to Resolve IR Code Confl icts

There are matching pairs of dip switches underneath the Switcher unit and under the
remote battery cover. Switch 1 & 2 on the Remote and Switch 3 & 4 underneath the unit
are the matching switches. These switches need to be matched for the remote to
communicate with the switcher. There are 4 possible sets of IR codes and at least one of
these sets should be able to resolve any IR confl icts with other home theater devices.
