• 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.
