completely sealed.

If you need to open the battery compartment, don't open it in a dusty or wet environment.

You should make sure that the battery cover is closed to ensure that dust and water cannot enter the battery

compartment.

Dirt, oil, or other products can damage the gasket on the battery compartment cover, resulting in a poor seal.

Every time you change the battery, inspect the gasket for damage. If the gasket is damaged, you can order a

replacement cover.
