CARE AND MAINTENANCE
PRECAUTIONS
LENS
Be careful that you do not directly
touch the lens surface with your
hands when cleaning it. Remove
dust or lint with a blower*. For
fingerprints or other stains that
cannot be removed with a blower,
wipe the lens with a dry soft cloth or
cleaning cloth for eyeglasses, using a
spiral motion that starts at the center
of the lens and working towards the
edges. Wiping too firmly or wiping
with a hard material may damage
the lens. If this fails, gently wipe the
lens using a cloth lightly dampened
with commercial lens cleaner.
MAIN BODY
After gently removing dust with a
blower, clean the body surface with a
soft, clean cloth. After use at a
seaside, wipe off salt that may be on
the body surface with a damp, soft,
clean cloth, and then wipe with a dry
cloth. Do not use benzene, thinner,
or other cleaners containing organic
solvents.
STORAGE
Water condensation or mold may
occur on lens surfaces because of
high humidity. Therefore, store the
product in a cool, dry place. After use
on a rainy day or at night, thoroughly
dry it at room temperature, then
store in a cool, dry place.

characteristics of the target.
Measurement may be inaccurate or fail in the
following cases:
• In snow, rain or fog
• Small or slender target
• Black or dark target
• Target has stepped surface
• Moving or vibrating target
• When measuring the surface of water
• Target measured through glass
• When the target is glass or a mirror
• When laser incidence to the target’s reflective
surface is oblique
