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
•
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.
•
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.
