Setting
Remote control
This projector provides two different remote control codes;
the factory-set, initial code (Code 1) and the secondary code
(Code 2). This switching function prevents remote control
interference when several projectors or video equipment
are operated at the same time.
When the projector is operated in "Code 2, " both the
projector and the remote control must be switched to
"Code 2. "
To change the code for the projector:
Select either "Code 1" or "Code 2" in this Setting Menu.
To change the code for the remote control:
Press and hold both the MENU and IMAGE buttons
together for more than 5 seconds. After changing the code,
make sure the remote control operates properly.
✔Note:
• When different codes are set on the projector and on the
remote control, any operation cannot be made. In that
case, switch the code on the remote control to fit the
code on the projector.
• if the batteries are removed from the remote control for a
long period of time, the remote control code will be reset.
Security (Alarm and PIN code lock setting)
This function allows you to use PIN code lock and Alarm
function to set the security for the projector operation.
PIN code lock
This function prevents the projector from being operated
by unauthorized persons and provides the following
setting options for security.
Off...... The projector is not locked with the PIN code.
On1...... Requires to enter a PIN code every time
turning on the projector.
On2...... Requires to enter a PIN code to operate the
projector once the power cord is unplugged;
