Removing dirt on the image sensor
The image sensor is very precise and delicate, so be sure to observe the following when
you do have to clean it yourself.
•
Blow off the dust on the surface of the image sensor with a commercially available blower
brush. Be careful not to blow too strongly.
•
Do not put the blower brush further inside than the lens mount.
•
Do not let the blower brush touch the image sensor as the image sensor may get scratched.
•
Do not use any objects except a blower brush to clean the image sensor.
•
If you cannot remove the dirt or dust with the blower, consult the dealer or Panasonic.
∫ For care of the viewfinder/eye cup
•
Before you remove stains on the viewfiner
and eyecup or start other types of cleaning,
remove the eyecup ( 1 ). Blow away the dust
on the viewfinder surface with a blower
(commercially available), and wipe the
surface lightly with a dry, soft cloth. Attach
the eye cup after the cleaning ( 2 ).
•
Be careful not to lose the eye cup.
•
Keep the eye cup out of reach of children to
prevent swallowing.
About the Lens
•
Do not press the lens with excessive force.
•
Do not leave the camera with the lens facing the sun as rays of light from the sun may cause it
to malfunction. Also, be careful when placing the camera outside or near a window.
•
When there is dirt (water, oil, and fingerprints, etc.) on the surface of the lens, the picture may
be affected. Lightly wipe the surface of the lens with a soft, dry cloth before and after taking
pictures.
•
Do not place the lens mount facing downwards. Do not allow the
lens mount contacts A to become dirty.
