Hiding the image

In order to draw the audience's full attention to the

presenter, you can use BLANK on the projector or remote control to hide the screen image. The word

'BLANK' appears in the corner of the screen while the image is hidden. When this function is activated with an audio input connected, the audio can still be heard.

Once BLANK is pressed, the projector lamp enters Economic mode automatically.

You can set the blank time in the SYSTEM SETUP: 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. The length of time can be set from 5 to 30 minutes in 5-minute increments.

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

No matter Blank Timer is activated or disabled, you can press any key on the remote control to restore the picture.

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.

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.

To activate the High Altitude Mode, go to the

SYSTEM SETUP: Advanced > High Altitude Mode, select On by pressing / on the projector or remote control. A confirmation message displays. Highlight Yes and press Mode/Enter.

Operation under "High Altitude Mode" may cause a higher decibel operating noise level because of increased fan speed necessary to improve overall system cooling and performance.

If you use this projector under other extreme conditions excluding the above, it may display auto shut-down symptoms, which is designed to protect your projector from over-heating. In cases like this, you should switch to High Altitude mode to solve these symptoms. However, this is not to state that this projector can operate under any and all harsh or extreme conditions.

Notice

We recommend you use the High Altitude Mode by selecting it whenever your environment is higher than 1500 m.

Do you want to turn High Altitude

Mode on?

Yes No

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

condition.
