CAMERA CARE TIPS
1. Never touch the reflex mirror, focusing
screen or AF contacts. Remove dust
with a blower brush.
3. Never touch the DX-contacts. Keep
clean with biower brush.
7. Clean the viewfinder eyepiece with a
soft, clean cloth. Do not use alcohol.
8. Clean glass surfaces such as the lens
with a blower brush; avoid using lens
tissue as much as possible. To remove
dirt and smudges, use soft cotton
moistened with pure alcohol and wipe
in a spiral motion from center to pe­
riphery. Be careful not to leave traces.
Caution
A spray gun-type blower may damage
the glass if used to clean the lens,
especially when ED glass is used for
the front lens element. To avoid
damage, hold the blower upright with
its nozzle more than 30cm (12 in.)
from the lens surface and keep the
nozzle moving so the stream of air is
not concentrated in one spot.
