Te s t P a t t e r n
Enable this function to display the grid test pattern, which helps
you adjust the image size and focus so as to check if the
projected image is free of distortion.
Closed Caption
• Closed Caption Enable
Activate the function by selecting On when the selected input
signal carries closed captions*.
*About caption
An on-screen display of the dialogue, narration, and sound
effects of TV programs and videos that are closed captioned
(usually marked as “CC” in TV listings).
• Caption Version
Select a preferred closed captioning mode. To view captions,
select CC1, CC2, CC3, or CC4 (CC1 displays captions in the
primary language in your area).
High Altitude
Mode
The mode is for operation in areas like high altitude or high
temperature environments. Activate the function when your
environment is between 1500 m–3000 m above sea level and
ambient temperature is between 0°C–30°C.
Do not use this function if your altitude is between 0 m and
1500 m and ambient temperature is between 0°C and 35°C. If
you turn on the mode under such a condition, the projector
will be over cooled.
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.
Password
For security purposes and to prevent unauthorized use, you may
set up password security for the projector. See "Utilizing the
password function" on page 29 for details.
• Change Password
You will be asked to enter the current password before changing
to a new one.
• Power On Lock
Limits use of the projector to only those who know the correct
password.
