Operating in a high altitude environment

We recommend you use the High Altitude Mode when your environment is higher than 3200 feet above sea level, or is hotter than 40°C, or whenever the projector will be used for extended periods of time (>10 hours) without shutdown.

To activate the High Altitude Mode, go to

SYSTEM SETUP: Advanced > High Altitude Mode, select On by pressing Left/

Right on the projector or remote control. A confirmation message displays. Highlight Yes and press 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.

WARNING

High Altitude Mode is used when the environment is higher than 3200 feet, or the temperature is over 40°C.

Do you want to turn the High Altitude Mode on?

Yes No

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.

Hiding the image

In order to draw the audience's full attention to the presenter, you can use BLANK on the projector and remote control to hide the screen image. Press any button (except LASER) on the projector and remote control to restore the image. The word 'BLANK' appears at the lower right 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.

You can set a time length in the SYSTEM SETUP:

Basic > Blank Timer menu to shut down the projector after a period of time when there is no action taken on the projector or remote control. 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 button (except LASER) anytime you want to restore the image.

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.
