Cleaning
Wipe the screen surface with a commercially available LCD cleaning kit to
remove fingerprints, dust, etc.
• When cleaning the lens surface, remove dust using a commercially
available blower. In case of dust that sticks to the surface, wipe it off with
a soft cloth or tissue paper slightly moistened with lens cleaning solution.
Wipe in a spiral pattern from the center to the outside. Do not spray lens
cleaning solution directly onto the lens surface.
• Do not touch the inside of the camera, such as lens contacts, or the mirror.
Since dust on the mirror or around the mirror may affect the autofocus
system, blow away dust using a commercially available blower. If dust
lands on the image sensor, it may appear on the photo image. Turn the
camera to the cleaning mode, then clean it using a blower (page 30). Do
not use a spray blower to clean the inside of the camera. Using this may
cause a malfunction.
• Do not use a cleaning solution containing organic solvents, such as
thinner, or benzine.
Clean the camera surface with a soft cloth slightly moistened with water,
then wipe the surface with a dry cloth. Do not use the following as they
may damage the finish or the casing.
• Chemical products such as thinner, benzine, alcohol, disposable cloths,
insect repellent, sunscreen or insecticide, etc.
• Do not touch the camera with the above on your hand.
• Do not leave the camera in contact with rubber or vinyl for a long time.
