Projector's autofocus feature ensures that the projected image is as sharp as possible without the user having to manually adjust the projector's focus. 

If  your Mars II Pro or Mars II projector loses focus and the image projected is blurry, please try the following steps:

1. Turn on Autofocus by selecting Settings > Projector > Auto Focus Correction > On.

2. Place the projector within 3 meters from the projection screen.

3. Slightly move the device or press and hold the "menu" button for 2-3 seconds to trigger the autofocus mechanism. If necessary, you could press the volume +/- buttons to manually adjust the focus when the autofocus symbol appears on screen.
