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. Unauthorised 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 accessory. If any device is not working

properly, take it to the nearest authorised service facility for

service.
