NOTE

The Color adjustment in the Display menu is only available with an active video source.

The image is cut in half or is cropped on one side.

The native resolution of the C20 is SVGA (800 X 600 pixels), and it offers compression for resolutions up to 1280 x 1024

(SXGA). The native resolution of the C60 is XGA (1024 x 768 pixels), and it also offers compression up to SXGA. The C20 will

expand images at 640 x 480 up to 800 x 600, and the C60 will expand images at 640 x 480 and 800 x 600 up to 1024 x

768.

Some computers run at resolutions higher than 1280 x 1024, which can cause display problems. For best results, make sure

your computer is set to the native resolution of the projector. If you're using a laptop, disable the internal display so the

image appears on the projection screen only. Additionally, in the Image menu of the projector, make sure that Resize is set

to standard.

If these suggestions do not help, make sure that the projector's system software is updated to the latest version.

The image will not focus, but I can make it larger or smaller.

Make sure that you are turning the focus ring rather than the zoom ring. The zoom ring is larger and more prominent, but

the focus ring actually sits in front of the zoom ring, right at the front of the lens.

The image appears squeezed vertically.

The Screen Aspect may be set to 16:9 (wide screen). A computer image requires a 4:3 aspect ratio. Press the Menu button

on the projector, then navigate to Setup. Select Screen Aspect and press the Source/Select button. Select 4:3.

The image disappears or the lamp shuts itself off after a period of time.

Make sure the DPMS mode (Display Power Management System) is disabled. When DPMS is enabled, the projector

turns the lamp off after 3 minutes of not detecting an active source. The projector will return to normal activity

immediately if it detects an active source. After 5 additional minutes, the projector turns completely off.

In the menu, navigate to Setup > System, and verify that DPMS enable is not checked.

The projector may be overheating, which is frequently the result of clogged dust filters.

Make sure that you have the latest software version installed. An enhancement in version 1.26 for both models

improved internal cooling, which reduces the likelihood of premature shutdown.

You can check your software version in the projector menus. Press the Menu button, then navigate to

Basic>System>Service>Info. Your version number should be 1.26 or higher. If it is version 1.17 or 1.18, upgrade

the software. You can do this yourself, or you can take the projector to an ASK Proxima Authorized Service Center

for a software upgrade.

If the problem persists, it is possible that there is an internal problem that requires repair. Take the projector to your

dealer or contact ASK Proxima Technical Support.
