Hiding the image

In order to draw the audience's full attention to the presenter, you can use ECO BLANK on the projector or remote control to hide the screen image. When this function is activated with an audio input connected, the audio can still be heard.

You can set the blank time in the SYSTEM SETUP: Basic > Operation Settings >

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.

If the preset time spans are not suitable for your presentation, select Disable.

No matter Blank Timer is activated or not, you can press most of the keys on the

projector or remote control to restore the picture.

To provide you a quick and friendly way to temporarily hide the screen image, the projector is equipped with a sensor to detect any object approaching the projection lens and enters blank status automatically in a short time once the object is within 30 degrees perpendicular to the sensor and 10 cm from the sensor. Moving the object away from the effective range will also return the projector to normal projection status within a few seconds.

Be sure the SYSTEM SETUP: Basic > Operation Settings > Auto Blank menu

is On.

The effective range of the sensor may vary according to the material and color of the blocking object.

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.Go to the SYSTEM SETUP: Basic > Panel Key Lock menu, and select On by

pressing / on the projector or remote control. A confirmation message appears.

2.Highlight Yes and press MODE/ENTER to confirm.

To release panel key lock, use the remote control to enter the SYSTEM SETUP: Basic > Panel Key Lock menu and press / to select Off.

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

•If you turn off the projector without disabling panel key lock, the projector will still be in locked status the next time it is turned on.

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 ambient temperature is between 0°C–35°C.

Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and ambient temperature is between 0°C and 35°C. The projector will be over cooled, if you turn the mode on under such a condition.

To activate the High Altitude Mode:

1.Press MENU/EXIT and then press / until the SYSTEM SETUP: Advanced menu is highlighted.
