Care And Maintenance - Nokia N91 User Manual

What if your battery is not authentic?
If you cannot confirm that your Nokia battery with the
hologram on the label is an authentic Nokia battery, please
do not use the battery. Take it to the nearest authorized
Nokia service point or dealer for assistance. The use of a
battery that is not approved by the manufacturer may be
dangerous and may result in poor performance and damage
to your device and its enhancements. It may also invalidate
any approval or warranty applying to the device.

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 contacts and calendar notes) before sending your
device to a service facility.
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.
