17 Connecting the Remote Control with the Lead Wire
Connecting the Remote Control with the Lead Wire
If you set up the projector for rear projection and want to use the remote control
to control the projector, you need to connect the remote control directly to the
projector with the optional lead wire. You might also need to directly connect
the remote control if anything is blocking the path between the remote control
and the projector.
To directly connect the remote control, connect one end of the lead wire to the
projector’s Remote jack. Connect the other end to the output terminal at the front
end of the remote control. Make sure both ends are plugged in securely.
