Freezing the image

Press FREEZE on the remote control to freeze the image. The word

'FREEZE' will display in the upper left corner of the screen. To release the function, press any key on the projector or remote control.

Even if an image is frozen on the screen, the pictures are running on the video or other device. If the connected devices have active audio output, you will still hear the audio even though the image is frozen on screen.

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 5°C–23°C.

Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and temperature is between 5°C and 28°C. The projector will be over cooled, if you turn the mode on under such a condition.

To activate the High Altitude Mode:

3.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.

Adjusting the sound

The sound adjustments made as below will have an effect on the projector speakers. Be sure you have made a correct connection to the projector audio input. See "Connections" on page 18 for how the audio input is connected.
