Locking control keys
With the control keys on the projector locked, you can prevent your projector settings
from being changed accidentally (by children, for example). When the Panel Key Lock is
on, no control keys on the projector will operate except POWER.
1. Go to the System Setup: Basic > Panel Key Lock menu, and select On by
pressing / on the projector or remote control. A confirmation message appears.
2. Highlight Ye s and press MODE/ENTER to confirm.
To release panel key lock, use the remote control to enter the System Setup: Basic >
Panel Key Lock menu and press / to select Off.
Keys on the remote control are still active when panel key lock is enabled.
If you press POWER to turn off the projector without disabling panel key lock, the
projector will still be in locked status the next time it is turned on.
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–30°C.
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
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 / to 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 21
for how the audio input is connected.
