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) before sending your
device to a service facility.
