Nokia C21 User Guide
TAKE CARE OF YOUR DEVICE
Handle your device, battery, charger and accessories with care. The following suggestions help
you keep your device operational.
• Keep the device dry. Precipitation,
humidity, and all types of liquids or
moisture can contain minerals that
corrode electronic circuits.
• Do not use or store the device in dusty or
dirty areas.
• Do not store the device in high
temperatures. High temperatures may
damage the device or battery.
• Do not store the device in cold
temperatures. When the device warms to
its normal temperature, moisture can form
inside the device and damage it.
• Do not open the device other than as
instructed in the user guide.
• Unauthorized modifications may damage
the device and violate regulations
governing radio devices.
• Do not drop, knock, or shake the device or
the battery. Rough handling can break it.
• Only use a soft, clean, dry cloth to clean
the surface of the device.
• Do not paint the device. Paint can prevent
proper operation.
• Keep the 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 info.
During extended operation, the device may feel warm. In most cases, this is normal. To avoid
getting too warm, the device may automatically slow down, dim display during a video call,
close apps, switch off charging, and if necessary, switch itself off. If the device is not working
properly, take it to the nearest authorized service facility.
RECYCLE
Always return your used electronic products, batteries, and packaging materials to dedicated
collection points. This way you help prevent uncontrolled waste disposal and promote the
recycling of materials. Electrical and electronic products contain a lot of valuable materials,
including metals (such as copper, aluminum, steel, and magnesium) and precious metals (such
as gold, silver, and palladium). All materials of the device can be recovered as materials and
energy.
