Boxlight CD-40m ユーザーズマニュアル

This section describes how to use and make adjustments to the 
projector. It also provides a reference to the keypad buttons and 
the options available from the on-screen menus.

Make sure you have powered up your equipment in the right 
order (page 11).

If the image doesn’t display completely, adjust the height of 
the projector (page 14) or center the image by adjusting its 
horizontal or vertical position (page 22). Be sure the projector 
is at a 90 degree angle to the screen.

If the image is out of focus, rotate the focus ring (Figure 9).

If the image appears to shimmer or if it has blurry vertical 
bars after you have adjusted the focus, turn Auto Image 
(page 21) off and then back on to reset the automatic sync and 
tracking. If that doesn’t clear up the image, turn Auto Image 
off and adjust the sync (page 21) and/or the tracking 
(page 22) manually.

If the colors don’t look right, adjust the brightness (page 18).

To focus the image, rotate the focus ring (Figure 9) until the image 
is clear.
