1. Remove battery cover from the back of the RMT4-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 RMT4-IR remote by pressing ONLY one button at a time. The indicator
light on the remote will flash 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 RMT4-IR ships with two batteries.

How to Resolve IR Code Conflicts
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 7 & 8 underneath the unit
are the matching switches. These switches need to be matched for the remote to
communicate with the switcher. Switch 1 on the remote is linked to switch 8 on the unit,
and switch 2 on the remote is linked to switch 7 on the unit. There are 4 possible sets of
IR codes and at least one of these sets should be able to resolve any IR conflicts with
other home theater devices.
