Cleaning and Storage
Cleaning
Do not use alcohol, thinner, or other volatile chemicals.
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 pumped to produce a stream of air out the other end). To remove
Lens 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.
Remove dust or lint with a blower. To remove fingerprints and other stains,
Monitor
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
cloth. After using the camera at the beach or other sandy or dusty
Body environment, wipe off any sand, dust, or salt with a dry cloth lightly
dampened with fresh water and dry thoroughly. Note that foreign matter
inside the camera could cause damage not covered by the warranty.
Storage
Remove the battery if the camera will not be used for an extended period. To prevent
mold or mildew, take the camera out of storage at least once a month.
Turn the camera on and release the shutter a few times before putting the camera
away again. Do not store the camera in any of the following locations:
Places that are poorly ventilated or subject to humidity of over 60%
Exposed to temperatures above 50°C (122°F) or below –10°C (14°F)
Next to equipment that produces strong electromagnetic fields, such as televisions
or radios
For storing the battery, follow the precautions in "The Battery" (A27) in "Caring for
