Operation

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.

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.

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:

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