not drop the phone or subject it to any strong impact. Do not carry your phone
in your back pocket. If you sit on it, the glass may break.
Protect the phone from temperature extremes. Do not leave it on the dashboard
of a car on a hot day, and keep it away from heaters and other heat sources. Store
it out of direct sunlight.
Do not store or use the phone in any location that is extremely dusty, damp, or

The Kyocera smartphone has a rechargeable lithium ion battery. You can charge the
phone battery in either of these ways:
Plug the power cable directly into the base of the phone. Plug the other end into
an AC power outlet.

outlet. Then place the phone in the sync
cradle.

wish, that can be charged in the rear
port of the cradle at the same time.
