MAINTENANCE AND
INSPECTION
WARNING
1. Be sure to disconnect the cable and remove the lens from
the camera before cleaning outside of the lens. Do not use
benzene, thinner, or other flammable substances to clean
the product. Otherwise it may cause a fire or electric shocks.
NOTE
1. Clean off any dust on the lens surface using a lens blower or
a soft lens brush. In case of getting fingerprints or stains on
the lens, use a clean cotton cloth moistened with commercial
lens cleaning fluid, or use lens cleaning paper. Gently wipe in
a spiral pattern from the center of the lens. Be careful not to
rub dust across the lens, which may scratch the lens surface.
2. Routine inspection about once a year is recommended,
depending on the conditions and environment of use.
Request overhaul, if needed.
