Using the front panel (all models)
One or more PINs must be configured before this procedure can be used. See
“Preparing the MLC for front panel lockout” on page 2-8. To lock/unlock the front
panel, you use the Display On/Off buttons to change modes and use the input
buttons as a numeric keypad.
N Make sure the projector or display is off before using a PIN to lock the front panel.
N Failure to configure the On or Off buttons to send display/projector commands
upon button release (instead of button press) may cause problems with the PIN
Mode feature. (If one On/Off button is pressed before the other, and the buttons
are configured to send commands at the button press, the first button’s actions
can be executed, preventing you from locking the front panel until the display’s
warm‑up or cooldown period finishes.)
