Using the front panel
One or more PINs must be configured before this procedure can be used. See
the MLC for Front Panel Lockout
on page 15. To lock or unlock the front panel,
you use the
Display On
/
Off
buttons to change modes and use the input buttons as a
numeric keypad (see images below).
NOTE:
Make sure the projector or display is off before using a PIN to lock the front panel.
NOTE:
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 actions of the first button can
be executed, preventing you from locking the front panel until the warm-up or
cooldown period of the display finishes.)
