Care and maintenance
Your device is a product of superior design and craftsmanship and should be treated with
care. The following suggestions will help you protect your warranty coverage.

the battery, and allow the device to dry completely before replacing it.

components can be damaged.
Do not store the device in hot areas. High temperatures can shorten the life of electronic
