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
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 Yes 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
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.
