2. Turn the trim pot in a clockwise fashion until it comes to a stop. Do not force
the trim pot beyond this point. Doing so may break the trim pot.
3. Slowly turn the trim pot counter-clockwise in millimeter increments until the
image stabilizes and all video noise disappears.
4. Carefully remove the adjustment tool.

IR Remote Channel Confi guration
Dip Switches 2 and 3 relate to the IR remote control channel that is used by the
HDMI Over CAT5 Receiver and RMT-4IR remote control. Dip Switch 2 and 3 on
the HDMI Over CAT5 Receiver must match Dip Switch 1 and 2 on the RMT-4IR
remote control. Each HDMI Over CAT5 Receiver and remote pair, should be set
to a different channel so that no two units do receive confl icting IR commands.
Please view the table below to set the channel on each of the HDMI Over CAT5
Receiver units and IR remote controls. The remote channel for the RMT-4IR is
located underneath the battery cover.
