Screw in the Locking Screw hole above the corresponding HDMI Port. Con-
nect an HDMI cable to the HDMI In 1 Port on the back of the HDMI Transmit-
ter. Insert a Locking Screw in the Lock Bolt hole above the HDMI Port on the

Display Device. Make sure that you use the HDMI In 2 and HDMI Out 2 Ports
instead of using the HDMI In 1 and HDMI Out 1 Ports as outlined in the
Installation steps.
Video source and destination have a one to one relationship, video cannot
be switched or split.
9. Connect the Universal Power Adapter to the DC 12V Power Port on both the
HDMI Transmitter and HDMI Receiver and the other end to an AC Electrical
Outlet.
