Operation 34
High Altitude
Mode (off)
A mode for operation in areas like high altitude or high temperature. We
recommend you use the High Altitude Mode when your environment is
higher than 3000 feet above sea level, or is hotter than 40
°C , or whenever
the projector will be used for extended periods of time (>10 hours)
without shutdown.
To activate the High Altitude Mode, select On by pressing Left 3/ Right
4on the projector or remote control. A confirmation message displays.
Press Auto.
Next time you turn on the projector, it will show a message pictured below
as a reminder during the start-up.
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.
Auto Off (off)
This function allows the projector to turn off automatically if no input
signal is detected after a set period of time. Press Left
3/ Right 4on the
projector or remote control to set the duration before the projector is
turned off. Selecting Off disables this function.
Economic
Mode (off)
Use this mode to reduce system noise and reduce power consumption by
20%. If this mode is activated, the light output will be reduced and result
in darker projected images.
Setting the projector in Economic mode extends the lamp timer
automatic shutdown feature. For more information on how the total
lamp hour is calculated, see
"Calculation of lamp hour" on page 37 .
We recommend you use the High Altitude Mode by selecting On
when your environment is higher than 3000 feet, or is hotter than 40°C.
