the 
A/V Mute button is pressed. The screen can be locked with a 
password to discourage theft and provides a way to identify the 
projector should it be stolen. See page 70.

altitudes above 7,500 feet 
(2,286 meters).

Once you have saved a new 
user’s logo, you cannot 
return to the factory default 
logo.
