Do
not
attempt to repair the

in
a dangerous electric
shock.
Leave
repairs to
an
authorized Nikon dealer
or send the unit directly to the manufacturer .
Be
sure to turn the power switch to the
"OFF"
position before opening the battery compartment to
replace the batteries

CARE
---------
Although you should always keep the lens surfaces
clean, rough cleaning must
be
avoided.
Wipe
with
a soft, clean cotton cloth moistened with a
lc
ohol
to remove grease or fingerprints from the
lens
surfaces.
If
you
use
ether
in
cleaning the lens, a smudge
sometimes appears on the surface
of
a multi-
coated
lens.
If
this happens, wipe it
again
with a
cotton cloth moistened with alcohol.
Keep
the
lens
cap
in
place whenever the
lens
is
not
in
use
.
Attach both the front and rear caps when the
lens
is
stored separately.
