Operation

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 the ambient temperature is between 0°C–30°C.

Do not use the High Altitude Mode if your altitude is between 0 m and 1499 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. Highlight Settings and press OK to enter.

2. Go to Advanced > High Altitude Mode and press OK.

3. Highlight On and press OK to confirm.

4. To leave the OSD, press until the projector returns to the home screen, or press

to go back to the home screen directly.

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

exhibit auto shut-down symptoms, which is designed to protect your projector from

overheating. 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.

Adjusting the sound

The sound adjustment functions displayed below will have an effect on the projector

speaker(s). Be sure you have made a correct connection to the projector audio input. See

"Connecting a computer" on page 17 for details on audio input connection when a

separate audio input cable is used to connect the projector.

Adjusting the sound mode

This project is preset with four sound modes to enrich your listening experience. You can

choose one of the four preset sound modes: Standard, Cinema, Music, and Game

based on your needs.

1. Highlight Settings and press OK to enter.

2. Go to Advanced > Audio Settings and press

OK to enter.

3. Highlight Sound Mode and press OK to open the

pop-up menu.

4. Highlight desired mode and press OK to confirm.

5. To leave the OSD, press until the projector

returns to the home screen, or press to go

back to the home screen directly.
