Operation

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. Press / or go to the SYSTEM SETUP: Basic > Panel Key Lock
menu, and select On by pressing / . A confirmation message
displays.
2. Highlight Ye s and press ENTER to confirm.
To release panel key lock, press and hold / on the remote control
or projector for 3 seconds.
You can also use the remote control to enter the SYSTEM SETUP: Basic
> Panel Key Lock menu and press / to select Off.
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–35°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 Ye s 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.
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.
Keys on the remote control
are still in use 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.
We recommend you use the High
Altitude Mode by selecting it whenever
your environment is higher than 1500
m.
Do you want to turn High Altitude
Mode on?
Yes No
