4 Grease the O-ring.
If the O-ring is not properly greased, it may
crack or peel, causing leaks. Grease the ring
if the surface appears dry. First, squeeze
about a centimeter (half an inch) of silicon
grease into a plastic bag and use your fi ngers
to spread the grease throughout the bag
(
q
). Next, insert the O-ring and massage
the bag to coat the ring ( w ). Use only grease
designated for use with the WP-N3. Do not
apply grease using cloth or paper, as these
may leave fi bers on the O-ring. Note that ap-
plying 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 protrud-
ing 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.
