4 Grease the O-ring.
If the O-ring is not properly greased, it may
crack or peel, causing leaks. If the surface of
the O-ring appears dry, place a drop of silicon
grease on your index fi nger and spread grease
on the O-ring by sliding it between your thumb
and index fi nger, evenly covering the ring. Do
not use cloth or paper, as these may leave fi bers on the O-ring. Note
that applying too much grease may cause foreign objects to adhere
more readily to the ring, preventing the case from sealing properly.
5 Replace the O-ring.
Making sure the O-ring and guide are free
of foreign objects, place the O-ring so that it
runs evenly at the same level all the way round
the O-ring guide, without undue stretching
or twisting and without protruding from the
guide.
D O-Rings
The O-ring requires periodic replacement. Replace the O-ring immediately if it is damaged,
cracked, warped, or has lost its elasticity. O-rings should be replaced at least once a year. Use
only silicon grease designated for use in this product; replacement O-rings and silicon grease
can be purchased from a Nikon camera retailer or Nikon-authorized service agent. Do not
use COOLPIX or NIKONOS O-ring lubricant (grease).
D Cleaning
Do not use detergents or volatile chemicals such as alcohol or thinner when cleaning the
case or O-ring. Failure to observe this precaution could result in damage to the case or
O-ring.
