Failure to confi gure 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 confi gured to send commands at the button press, the fi rst button’s actions
can be executed, preventing you from locking the front panel until the display’s
warmup or cooldown period fi nishes.)
