If the CMOS surface gets dust and dirt, this will lead to degraded
imaging results.To avoid poor results, cleaning may become
necessary.
1. For smaller dust and stains, it is first recommended to try to use
software flat-field processing. This will improve image quality without
needing to open your camera.
2. for the larger dust and dirt which a flat field can not eliminate, you
can follow the steps below to remove the infrared filter and clean the
detector's optical surface.
> Remove the four screws holding the shade film in place;
> Counterclockwise rotation of the filter ring will allow the filter to be
removed;
> Carefully remove the infrared filter, paying attention not to touch or
scratch the surface;
> Cleaning the surface of the CMOS and reverse the steps to
reassemble the camera.

• Using a clean rubber bulb, gently blow dust off to clean the surface.
• For dust which can not be blown off, use lens paper or a commercially available SLR
Camera Cleaning Kit to clean the surface of the CMOS.
• Lens paper: Take a single sheet of lens paper and fold it once or twice (do not fold
too much, and lens paper is easy to produce sharp edges can scratch the CMOS glass
surface). Wet the paper with some distilled water, and, gently drag the lens paper over the
CMOS to maintain an appropriate pressure to wipe off dust and stains.
