Setting
Remote control
Two different remote control codes are assigned to this projector;
the factory-set normal code (Code 1) and the secondary code
(Code 2). This switching function prevents interference with
different remote controls when several projectors or video
equipment nearby are used at one time.
When operating the projector in "Code 2", the code for both the
projector and remote control must be switched to "Code 2".
To change the code of the projector :
Set the remote control in the Setting Menu to "Code 2."
To change the code of the remote control :
Press and hold both MENU and IMAGE buttons on the remote
control for more than 10 seconds. After changing the code, make
sure the remote control operates properly.
To return to the normal code (Code 1), follow the above steps to
operate both the projector and remote control.
✔
Note:
• When the batteries of the remote control are replaced, the remote control code
automatically returns to the normal code (Code 1).
