Observe the following precautions when handling O-rings:
• The O-ring requires periodic replacement. Replace the O-ring immediately if it is damaged,
cracked, warped, or has lost elasticity. O-rings should be replaced at least once a year; do not
use a worn O-ring or a type of O-ring not designated for use in this product.
• To prevent damage to the O-ring, use the O-ring remover when removing the ring from
the case. Do not use metal objects or objects with sharp points when removing the O-ring.
• Do not use force when removing or positioning the O-ring. Excessive force may perma-
nently stretch the ring, causing the case to leak.
• To prevent wear, use only silicon grease designated for use with this product (
use COOLPIX or NIKONOS O-ring lubricant (grease) or other types of silicon grease.
