Maintenance

This section describes how to maintain the O-ring and waterproof case.

Caring for the O-Ring

The WP-N1 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 de- scribed below before each use, and check for the presence of foreign ob- jects on the O-ring each time the case is opened, however briefly.

1Remove the O-ring.

Use the O-ring remover to remove the

O-ring as shown.

DDo 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.

2Inspect the O-ring.

Remove old silicon grease and other foreign objects with a soft 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.

3Inspect the O-ring guide.

Use a blower or cotton swab to remove any foreign 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.
