setting by RS-232C commands from the computer. (See page 63.)
• When using slave setting in combination with Keylock Level B or C, all the buttons on
the projector and the remote control are disabled. Use the SAPS or RS-232C commands
to release slave and Keylock setting and enable buttons to operate.
Without a computer, you can release slave and Keylock setting by entering the buttons
