Panasonic Lumix DMC-GH4A Basic Operating Instructions Manual page 113

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.
Battery
Always remove the battery after use.
•
Place the removed battery in a plastic bag, and store or keep away from metallic objects (clips, etc.).
If you drop the battery accidentally, check to see if the body of the battery and the
terminals are damaged.
•
Inserting a damaged battery in the camera will damage the camera.
Bring charged spare batteries when going out.
•
Be aware that the operating time of the battery becomes shorter in low temperature conditions
such as at a ski resort.
•
When you travel, do not forget to bring the battery charger (supplied) and the AC cable
(supplied) so that you can charge the battery in the country that you are travelling in.
Dispose of unusable battery.
•
The battery has a limited life.
•
Do not throw the battery into fire because it may cause an explosion.
Do not allow battery terminals to come into contact with metal objects (such as
necklaces, hairpins, etc.).
•
This can cause short-circuiting or heat generation and you may be badly burned if you touch a
battery.
