Network services and costs
Your device is approved for use on the
(E)GSM 900 and 1800 MHz networks. To use
the device, you need a subscription with a
service provider.
Using network services and downloading
content to your device requires a network
connection and may result in data traffic
costs. Some product features require
support from the network, and you may need
to subscribe to them.
Take care of your device
Handle your device, battery, charger and
accessories with care. The following
suggestions help you protect your warranty
coverage.
• Keep the device dry. Precipitation,
humidity, and all types of liquids or moisture
can contain minerals that corrode electronic
circuits. If your device gets wet, remove the
battery, and allow the device to dry.
• Do not use or store the device in dusty
or dirty areas. Moving parts and electronic
components can be damaged.
• Do not store the device in high
temperatures. High temperatures can
shorten the life of the device, damage the
battery, and warp or melt plastics.
• Do not store the device in cold
temperatures. When the device warms to its
normal temperature, moisture can form
inside the device and damage electronic
circuits.
• Do not attempt to open the device other
than as instructed in the user guide.
• Unauthorised modifications may
damage the device and violate regulations
governing radio devices.
• Do not drop, knock, or shake the device.
Rough handling can break internal circuit
boards and mechanics.
• Only use a soft, clean, dry cloth to clean
the surface of the device.
• Do not paint the device. Paint can clog
moving parts and prevent proper operation.
• Switch off the device and remove the
battery from time to time for optimum
performance.
• Keep your device away from magnets or
magnetic fields.
• To keep your important data safe, store
it in at least two separate places, such as your
device, memory card, or computer, or write
down important information.
