O-ring using your fingertips and a small amount of silicone grease until
there is a thin film covering the complete surface. DO NOT stretch the O-ring.
4. Before replacing the O-ring, visually inspect the groove in the battery
compartment cap for hair, sand, lint, or other debris and wipe clean as
necessary.
5. Install the O-ring in the groove at the base of the battery compartment cap,
making sure that it is seated uniformly, with no twists or loose areas. Be
careful not to stretch the O-ring.
