Options menu

In this menu, global settings for the projector can be made.

1. Background Color: Allows you to choose the color of the background screen that will be displayed when

there is no input signal detected.

2. OSD Off (Secs): Sets the length of time the OSD will remain active after your last button press. The range is

from 5 to 60 seconds.

3. Sleep Timer (Min): Sets the auto-shutdown timer. The timer can be set to a value between 10 minutes and 3

hours.

4. OSD Position H: Adjusts the horizontal position of the OSD.

5. OSD Position V: Adjusts the vertical position of the OSD.

6. Reset Settings: Returns all image settings of the current source to the factory preset values.

Setup menu

This menu contains items necessary for basic image setup.

1. Language: Sets the language for the OSD menus.

2. Mirror: The projector can be installed on a ceiling or behind a screen, or with one or more mirrors. There

are four settings for choice. Contact your dealer for the ceiling mount bracket if you need to install the

projector on a ceiling. See page 14 for more information.

3. High Altitude: This item is designed for those who use the projector in extreme environments, like high

temperature or high altitude. We recommend you select Ye s when your environment is higher than 3000

feet, or is hotter than 40°C.

Operation with Ye s selected may caused a higher decibel operating noise level because of increased fan

speed necessary to improve over-all cooling system and performance.

If you use the projector under other extreme environments 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 Yes to solve these symptoms. However, this is not to state that this projector can operate

under any and all harsh and extreme environments.

4. Black Level: The grayscale video signal is measured in IRE units. In some areas which use NTSC TV

standard, the grayscale is measured from 7.5 IRE (black) to 100 IRE (white); however, in other areas which

use PAL equipment or Japanese NTSC standard, the grayscale is measured from 0 IRE (black) to 100 IRE

(white). We suggest that you check the input source if it is with 0 IRE or 7.5 IRE, then select accordingly.

5. Keystone: Corrects for trapezoidal distortion resulting from the angle of projection. It can provide

correction of up to ± 12 degrees.

6. Pattern: It will be displayed with the aspect ratio setting made using the Aspect Ratio function of the

DISPLAY menu. Use this pattern when installing the projector, even if there is no input signal. Use it to

adjust the image size and the focus.

7. Lamp

• Lamp Type: Sets 250W or 200W as the power type of your projection.

• Lamp Hours:

i. Lamp Hours: Shows the total time of the lamp has been used.

ii. Lamp Rest Rate: Shows the percentage of the rest lamp life.

• Reset Lamp Timer: Resets the lamp timer. This should only be done after the lamp has been replaced.

8. Dust Filter

• Dust Filter Hours: Shows the total time of the filter has been used.

• Reset Dust Filter Timer: Reset the dust filter timer. This should only be done after the filter has been

replaced.
