Epson powerlite 1700c 사용자 설명서

■

Brightness Control

Lets you select from two levels of brightness. The 

Low

 setting 

reduces power consumption and noise, and extends the lamp’s 
operating life.

■

Volume

Raises or lowers the volume of the projector’s speaker.

To prevent unauthorized use of the projector, you can do the 
following:

■

Assign a password; this can be disabled for a set period if you want 
to loan the projector to someone. 

■

Create an identifying user logo that is displayed at startup and/or 
when the 

A/V Mute

 button is pressed. See page 53.

■

Disable the projector’s buttons; this is useful, for example, if 
you’re projecting in a classroom and you want to ensure that no 
one touches the projector’s buttons while you’re using the remote 
control. See page 55. 

If you create a user’s logo for the projector, you can set up the logo so 
it is displayed as the startup screen and/or AV/Mute screen. 
Unauthorized users cannot turn it off or change it. This feature is 
intended to discourage theft and provides a way to identify the 
projector should it be stolen. 

To prevent unauthorized use, you can assign the projector a password. 
If you do, a screen will appear requesting the password whenever the 
projector is plugged in and turned on. If an incorrect password is 
entered three times in succession, the projector’s operation is locked 
and the power cord must be disconnected and reinserted to redisplay 
the password screen. If an incorrect password is entered thirty times in 
succession, the user must contact Epson to unlock the projector.
