DEVICE BUTTONS
AUTOMATIC SWITHCING
Automatic swithcing is done very easily. Whenever you power on your device on a
certain input, that input will become active. If you power down the device on that input,
the switcher will revert back to the previous input that was active.
The remote and input select button will always allow you to switch manually. The remote
will switch discretely to any input, while the input select button will allow you to toggle
between inputs.

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.

IR CODE CONFLICTS
How to Resolve IR Code Conflicts
If you are expriencing IR conflicts, you can change the IR Code of the remote and switcher.
You can do so by holding the Enhance button down for 5 seconds and wait for the LED's
to flash in front of the unit. The LED's will flash the current IR channel. Press the Input
button to select which IR Code you want to set both the switcher and remote to. Press the
enhance button to finish. If this does not work, please call Gefen's tech support for further
assistance.
