Hiding the image

In order to draw the audience's full attention to the presenter, you can use on the

projector or Blank on the remote control to hide the screen image. Press any key on the

projector or remote control to restore the image. The word 'BLANK' appears at the lower

right corner of the screen while the image is hidden.

You can set the blank time in the

SYSTEM SETTING: BASIC > Blank Timer menu to

let the projector return the image automatically after a period of time when there is no action

taken on the blank screen.

Once Blank is pressed, the projector enters Economic mode automatically.

CAUTION

Do not block the projection lens from projecting as this could cause the blocking object to

become heated and deformed or even cause a fire.

Locking control keys

With the control keys on the projector locked, you can prevent your projector settings from

being changed accidentally (by children, for example). When the Panel Key Lock is on, no

control keys on the projector will operate except POWER.

1. Press on the projector or Lock on the remote control, or go to the

SYSTEM

SETTING: BASIC > Panel Key Lock menu

, and select On by pressing / on

the projector or remote control.

2. A confirmation message is displayed. Select Yes to confirm.

To release panel key lock, press and hold on the projector or Lock on the remote

control for 3 seconds.

You can also use the remote control to enter the SYSTEM SETTING: BASIC > Panel

Key Lock menu and press / to select Off.

• Keys on the remote control are still functional when panel key lock is enabled.

• If you press POWER to turn off the projector without disabling panel key lock, the

projector will still be in locked status the next time it is turned on.

Freezing the image

Press Freeze on the remote control to freeze the image. The word 'FREEZE' will be

displayed in the upper left corner of the screen. To release the function, press any key on the

projector or remote control.

Even if an image is frozen on the screen, the pictures are running on the video or other

device. If the connected devices have active audio output, you will still hear the audio even

though the image is frozen on screen.

Operating in a high altitude environment

We recommend you use the High Altitude Mode when your environment is between 1500

m–3000 m above sea level, and temperature is between 0°C–35°C.

CAUTION

Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and temperature

is between 0°C and 35°C. The projector will be over cooled, if you turn the mode on under

such a condition.
