Caring for the O-ring
The WP-CP4 uses an O-ring to form a watertight seal. Improper handling of
the O-ring can produce leaks. Check the condition of the O-ring as described
below before each use, and check for the presence of foreign matter on the
O-ring each time the case is opened, however briefl y.
Remove the O-ring
Pinch the O-ring lightly between two fi ngers to
form a loop. Take hold of the loop and remove
the O-ring from the case.
Do Not Use Force or Sharp Objects
The case may leak if the O-ring is forcibly stretched
or damaged through the use of edged or pointed
objects, including fi ngernails and metal tools.
Inspect the O-ring guide
Use a blower or cotton swab to remove any for-
eign objects from the watertight channel and all
parts of the case that come into contact with the
O-ring. Be sure to remove any threads left behind
by the swab.
Replacing the O-ring
The O-ring requires periodic replacement. Replace the O-ring immediately if it is dam-
aged, cracked, warped, or has lost its elasticity. O-rings should be replaced at least once
a year. Use only COOLPIX O-ring grease designated for use in this product; replacement
O-rings and O-ring grease can be purchased from a Nikon camera retailer or Nikon-au-
thorized service agent. Do not use NIKONOS O-ring lubricant (grease).
Inspect the O-ring
Remove old O-ring grease and other foreign mat-
ter with tissue paper or a soft, dry cloth, taking
care not to leave tissue or threads on the O-ring.
Gently bend the O-ring to check for cracking or
other damage.
