Why would I need to change the remote channel?

In some instances, the 8x4 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 RMT-16IR 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 RMT-16IR
remote control and the 8x4 Matrix for HDMI use. The IR channel is confi gured
independently on the RMT-16IR remote control and the 8x4 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 RMT-16IR remote control and also inside the
8x4 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 RMT-16IR remote control

The IR channel DIP switches for the 8x4 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
