How to Control the 4x1 HDMI Switcher

RMT4-IR INSTALLATION

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.

The optional IR extender allows you to

relocate your HDMI Switcher and still have

IR control of the HDMI Switcher

IR EXTENDER INSTALLATION

How to Connect the IR Extender

1 Plug the IR extender into the Remote port on the front of the Switcher Unit

2Flip the Dip Switch 1 underneath the unit to the ON position

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 1 & 2 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.
