30 Making Basic Adjustments
3. Choose from these options:
■ Lens Lock
disables the focus, zoom, and lens shift. If you try to use one of these
functions, a lock icon appears on the screen.
■ Child Lock
to disable the Ppower button on the projector’s control panel unless it is
pressed for about 3 seconds. (You can use the Ppower button to turn it off,
however.) Since you can still use the remote control to turn on the projector, you
may want to keep it away from children’s reach.
■ Control Panel Lock
to disable all the buttons on the projector’s control panel,
except for the Ppower button. A lock icon appears on the screen whenever you
press a button with Control Panel Lock turned on. To cancel Control Panel Lock,
press and hold the
Enter
button on the projector’s control panel for at least 7
seconds.
4. Press
Menu
to exit the menu system.
If you turned on the Control Panel Lock, the projector buttons are now locked.
If you turned on the Child Lock, turn off the projector and let it cool down. The Child
Lock takes effect after the cool-down period.
Caution: If the Direct Power On setting is turned on (see page 44), using the main power
switch can cause the projector to start even though the Child Lock is in use.
