RMT8-IR INSTALLATION
1. Remove battery cover from the back of the RMT8-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. Underneath the unit are a set of dip switches that need to match the switches on the
remote. Find and remove the silver sticker to show the dip switches underneath the
unit. Verify that switches 1 & 2 on the unit are both on the down (OFF) position. There
are 4 possible sets of IR Codes which at least one should relieve any IR conflicts with
other Home Theater devices.
5. Test the RMT8-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 RMT8-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.
