15 Using the projector keypad buttons Most buttons are described in detail in other sections, but here is an overvi ew of their functions: Pow er– turns the projector on and off. Menu– opens the on-screen menus. Select– confirms choices made in the menus.
16 Using the remote control The remote uses two (2) provided AAA batteries. They are easily installed by sliding the cover off the remote’s back, aligning the + and - ends of the batteri es, sliding them into pl ace, and then replacing the cover.
17 Optimizing video images After the video device is connect ed properly and the image is on the screen, you can opt imize the image using the onscreen menus. Change the Aspect ratio. Aspect ratio is the ratio of the image w idth to image height. TV screens are usually 1.
18 The menus are grouped by usage: The Picture menu provi des image adjustments. The Settings menu provides set-up type adjustments that ar e not changed often. The About menu provides a read- only display of information about the projector and source.
19 Native : this mode bypasses the internal scaler, displaying the image with no resizing. Since the native resolution is 1280x720 and 4x3 video images are approximately 640x480, 4x3 images will always be smaller than the display and will be centered in the display.
20 Natural Wide : this mode stretches a 4:3 image to fill the entire 16:9 screen. The center two-thirds of the image is unchanged; the edges of the image are stretched. Presets : This allows you to customize settings and save the settings to be restored later.
21 Advanced settings TrueLife : This option refers to Faroudja’s TrueLife processing of the image. All standard definition interlaced vi deo signals (composite, S-video and component) are routed through this processor. Extended and High Definition progressive component sources are not routed though this processor by default.
22 Color Control : allows you to individually adjust the gain (relative warmth of the color) and the offset (the amount of black in the color) of the r ed, green, and blue colors. Gamma : Gamma tables contain preset intensity configurations optimized for the input source.
23 The Source Enable feature is used to eliminate certain sources from this search, which will speed the search. By default, the check boxes for all sources are checked. Uncheck a source’s box to eliminate it from the search. System All options in this menu toggle between on and off.
24 Blank Screen : determines what color displays w hen you press the Blank button on the remote or when no source is active. Language : allow s you to select a language for the onscreen display of menus and messages. Service Menu Use these features, hi ghlight them and press Select .
25 Replacing the projection lamp The lamp hour timer in the A bout menu counts the number of hours t he lamp has been in use. After 1980 hours, the message “Change lamp” briefly appears on the scr een at each startup. To maintain optimal video performance, we recommend changing the lamp a fter 2000 hours, depending on usage.
