• Do not store the device in high or cold temperature. High
temperatures can shorten the life of electronic devices,
damage batteries, and warp or melt certain plastics. When
the device warms to its normal temperature from a cold
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. Only use a soft, clean, dry
cloth to clean the surface of 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.
• Backup all 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.
