Using the Projector Security Features

You can also reset the lamp usage timer or restore all the projector settings to their original 
values. Follow these steps:

1. Press the 

Menu

 button on the remote control.

2. Open the 

Reset

 menu.

3. Do one of the following:

■

Select 

Reset Lamp Hours 

to clear the lamp usage timer and reset it to zero. 

You should reset the lamp timer only when you install a new projector lamp. See 
page 63 for more information.

■

Select 

Reset All 

to return all projector settings to their original defaults (except User 

Button, Language, and Lamp Hours).

To prevent unauthorized use of the projector, you can:

■

Create a custom screen that is displayed at startup and/or when 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 52 for information on creating 
your own startup screen. 

■

Lock the projector with a password, or enable your iPod to act as a key. For more 
information, see page 54.

■

Disable the projector’s buttons; this is useful, for example, in a classroom when you want 
to ensure that no one touches the projector’s buttons while you’re using the remote 
control. See page 53 for more information.
