Cleaning mode — Removing dust on the CCD
If dust or dirt gets on tshe CCD, black dots may appear in the picture. If this
happens, contact your Olympus Authorized Service Center to have the CCD
physically cleaned. The CCD is a precision device and is easily damaged.
When cleaning the CCD yourself, be sure to follow the instructions below.
If a battery is used and power runs out during cleaning, the shutter will close,
which may cause the shutter curtain and mirror to break.

Press the shutter button fully.
• The mirror goes up and the shutter curtain
opens.

Clean the CCD.
• Carefully blow off any dust on the surface of
the CCD by using a mechanical blower
(commercially available).
7
Be careful not to catch the mechanical
blower in the shutter curtain when
turning the power off to finish cleaning.
• If the camera turns off, the shutter curtain closes, causing the mirror to fall.
Notes
• Be careful to not let the mechanical blower (commercially available) touch the CCD.
If the blower touches the CCD, the CCD will be damaged.
• Never put the mechanical blower behind the lens mount. If the power turns off, the
shutter closes, breaking the shutter curtain.
• Do not use anything other than the mechanical blower. If high-pressure gas is
sprayed onto the CCD, it will freeze on the CCD's surface, damaging the CCD.
