 Petroleum benzine and absolute alcohol used for cleaning are highly flammable. Be careful when handling these
materials, particularly around open flames or when turning the power switch on or off.

Cleaning Lenses

Keep the lens free of dust and fingerprints. If there is contamination on the lenses or filters, image quality decreases. If any
of the lenses become dirty, clean them by following the procedure given below.
■ Cleaning light dirt (dust)
(1) Blow dust off using an air blower.
(2) If this is insufficient, brush away dust with a soft brush or wipe away gently with a piece of gauze.
■ Cleaning tough dirt (fingerprint or grease)
Moisten lightly a piece of soft, clean cotton cloth, lens tissue, or gauze with absolute alcohol (ethyl or methyl alcohol) and
wipe the dirt off.
Tips on wiping
Do not reuse cotton cloth, lens tissue, or gauze that has already been used.
