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.

Keep the device dry. Precipitation, humidity, and all types of
liquids or moisture can contain minerals that will corrode
electronic circuits. If your device does get wet, remove the
battery, and allow the device to dry completely before replacing it.

Do not use or store the device in dusty, dirty areas. Its moving
parts and electronic components can be damaged.

Do not store the device in hot areas. High temperatures can
shorten the life of electronic devices, damage batteries, and
warp or melt certain plastics.

Do not store the device in cold areas. When the device returns
to its normal temperature, moisture can form inside the device
and damage electronic circuit boards.

Do not attempt to open the device other than as instructed in
this guide.

Do not drop, knock, or shake the device. Rough handling can
break internal circuit boards and fine mechanics.

Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean the device.

Do not paint the device. Paint can clog the moving parts and
prevent proper operation.

Use only the supplied or an approved replacement antenna.
Unauthorized antennas, modifications, or attachments could
damage the device and may violate regulations governing
radio devices.

Use chargers indoors.

Always create a backup of data you want to keep, such as
contacts and calendar notes.

To reset the device from time to time for optimum
performance, power off the device and remove the battery.

These suggestions apply equally to your device, battery, charger,
or any enhancement. If any device is not working properly, take it
to the nearest authorized service facility for service.

Note: Before sending your device to a service facility,
create a backup of data you want to keep such as
contacts and calendar notes.
