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.
CAUTION
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 on the projector or MENU/EXIT 
on the remote control and then press  /  until 
the SYSTEM SETTING: Advanced menu is 
highlighted.
2. Press  to highlight High Altitude Mode and 
press   /  to select 1 or 2. 
3. A confirmation message is displayed.
4. Highlight 1 and press MODE/ENTER on the projector or remote control.
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.

displayed prompting you. 
If you dont respond in a few seconds, the 
message will disappear.
2. Press   a second time.
3. Disconnect the power cord from the wall 
socket if the projector will not be used in an 
extended period of time.
CAUTION
• To protect the lamp, the projector will not respond 
to any commands during the cooling process.
• Do not unplug the power cord before the projector 
shutdown sequence is complete.
