PIXEL MAPPING and dust reduction
The PIXEL MAPPING feature allows the camera to check and adjust the CCD and
image processing functions. It is not necessary to operate this function frequently.
Approximately once a year is recommended. After using the monitor or taking
continuous shots, wait for at least one minute before using the PIXEL MAPPING
function to ensure that it operates correctly. Dust reduction also works at the same
time to remove dust on the CCD.
Cleaning and Checking the CCD
This camera incorporates a dust reduction function to keep dust from getting on the CCD and to
remove any dust or dirt from the CCD surface with ultrasonic vibrations. Dust reduction works
when the power switch is set to ON. This function also operates whenever PIXEL MAPPING is
activated.
Since dust reduction is activated every time the camera's power is turned on, the camera should
be held upright for the dust reduction function to be effective.
Note
● The following matter is not removed with the dust reduction function:
– Sticky matter (solvent, etc.)
– Lightweight particles such as cotton dust
– Microscopic dust particles not visible to the naked eye
CLEANING MODE
The dust reduction function will remove most dirt or dust on the CCD. However, when
dust or dirt is not removed completely, black dots may appear in the picture. If this
happens, contact your Olympus Authorized Service Center to have the CCD physical
cleaned. The CCD is a precision device and is easily damaged. When cleaning the
CCD on your own, be sure to follow the instructions below.
When cleaning the CCD, the specified AC adapter should be used. 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.
Note
● 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.
