80 Phone Care
Treat the phone gently. The touch-sensitive screen contains a glass
element. Do not drop the phone or subject it to any strong impact. Do not
carry your Kyocera 7135 smartphone in your back pocket. If you sit on it,
the glass may break.
Protect the Kyocera 7135 smartphone 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 wet.
Use a soft dry cloth to clean the screen.
Avoid using suntan lotion around the phone. Chemicals in suntan lotions
can damage your phone.
