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:

1.Press Menu/Exit and then press / until the SYSTEM SETUP: Advanced menu is highlighted.

2.Press to highlight High Altitude Mode and press / select On. A confirmation message displays.

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 "Connection" on page 18 for how the audio input is connected.

Muting the sound

To temporarily turn off the sound:

1.Press Menu/Exit and then press / until the SYSTEM SETUP: Advanced menu is highlighted.

2.Press to highlight Audio Settings and press Mode/Enter. The Audio Settings page displays.

3.Highlight Mute and press / to select On.

Adjusting the sound level

To adjust the sound level, press Volume +/- on the remote control, or:

1.Repeat steps 1-2 above.

2.Press to highlight Volume and press / to select a desired sound level.

Turning off the Power on/off ring tone

To turn off the ring tone:

1.Repeat steps 1-2 above.

2.Press to highlight Power on/off ring tone and press / to select Off.

The only way to change Power on/off ring tone is setting On or Off here. Setting the sound mute or changing the sound level will not affect the Power on/off ring tone.
