Why would I need to change the remote channel?
In some instances, the 4x4 Matrix for HDMI may use IR codes that confl ict with other IR
remote control devices. The unit may switch inputs when another brand IR remote control is
used or the RMT16-IR may cause other brand IR controlled devices to behave unexpectedly.
I am experiencing the issues listed above. What do I do?
In these cases it is recommended to change the IR channel that the RMT16-IR remote control
and the 4x4 Matrix for HDMI use. The IR channel is confi gured independently on the RMT16-
IR remote control and the 4x4 Matrix for HDMI but the channel selection must match on both
units for proper operation.
How Do I change the Remote Channel?
There are service DIP switches on the RMT16-IR remote control and also inside the 4x4
Matrix for HDMI. Use the diagrams below to locate and change the IR channel to one that is
not the default. Remember that the channel must match on both the unit and remote control
for successful operation.

Remove the battery cover on the rear side of the RMT16-IR remote control
to expose the DIP switches.
The IR channel DIP switches for the 4x4 Matrix for HDMI are located on an 8 bank DIP switch inside of the unit
and on its main-board. To open the unit, remove all screws on the underside and side of the unit. Remove all HEX
screws on the rear panel. This includes the screws above each HDMI port and on each side of the RS-232 serial
communications port. Carefully slide the unit apart. Locate DIP switches 3 and 4. Once adjustments are complete
replace all screws and.
