Care and maintenance
Your device is a product of superior design and craftsmanship
and should be treated with care. The suggestions below 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 a soft, clean, dry cloth to clean any lenses (such as
camera, proximity sensor, and light sensor lenses).
• 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
addresses and calendar notes) before sending your device
to a service facility.
• To reset the device from time to time for optimum
performance, power off the device, and remove the
battery. Make back-up copies of all important data.
All of the above 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.
