Caring for the Camera

Cleaning

 

Avoid touching glass parts with your fingers. Remove dust or lint with a blower

 

(typically a small device with a rubber bulb attached to one end that is

Lens

pumped to produce a stream of air out the other end). To remove fingerprints

or other stains that cannot be removed with a blower, wipe the lens with a soft

 

cloth, using a spiral motion that starts at the center of the lens and working

 

toward the edges. If this fails, clean the lens using a cloth lightly dampened

 

with commercial lens cleaner.

Monitor

Remove dust or lint with a blower. To remove fingerprints and other stains,

clean the monitor with a soft, dry cloth, being careful not to apply pressure.

 

 

Use a blower to remove dust, dirt or sand, then wipe gently with a soft, dry

Body

cloth. After using the camera at the beach or seaside, wipe off any sand or salt

with a dry cloth lightly dampened with fresh water, then dry thoroughly. Note

 

that foreign matter inside the camera could cause damage not covered by the

 

warranty.

 

 

Do not use alcohol, thinner, or other volatile chemicals.
