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. One battery is required for operation, the
second battery is complimentary.
How to Operate the IR Extender Eye (optional)
Plug in the IR extender eye to the extender port on the back of the switcher. As soon as
the IR extender eye is plugged in you can extend your IR signal. The IR extender eye
does not come included in the package.
IR CODE CONFLICTS
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 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 conflicts with other home theater devices.

IR CODES
In the event of IR conflicts, please do the following:
1. Remove the battery cover from the back of the RMT4-IR remote.
2. Locate the Dip Switches above the batteries.
3. Switch the Dip Switches on the RMT4-IR to any of the combinations pictured below.
4. Dip Switches 1 and 2 in the RMT4-IR correspond with Dip Switches 3 and 4 on the
bottom of the 4x1 DVI Switch respectively. Switch the switches on the bottom of the
4x1 DVI Switch to match the dip switches on the RMT4-IR. The 4x1 DVI Switcher is
now set to a new IR Code.
