•
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 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.
•
Always create a backup of 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.
These suggestions apply equally to your device, battery,
charger, or any accessory. If any device is not working
properly, take it to the nearest authorised service facility for
service.
Recycle
Always return your used electronic products, batteries, and
packaging materials to a dedicated collection point. This way
you help prevent uncontrolled waste disposal and promote
the recycling of materials. More detailed information is
available from the product retailer, local waste authorities,
national producer responsibility organisations, or your local
Nokia representative. Check how to recycle your Nokia
products at , or if browsing on a
mobile device.
The crossed-out wheeled-bin symbol on your product,
battery, literature, or packaging reminds you that all
electrical and electronic products, batteries, and
accumulators must be taken to separate collection at the end
of their working life. This requirement applies in the
European Union. Do not dispose of these products as unsorted
municipal waste. For more environmental information, see
the product Eco-Declarations
Additional safety information
Note: The surface of this device does not contain nickel in
the platings. The surface of this device contains stainless
steel.
Magnets and magnetic fields
Keep your device away from magnets or magnetic fields.
Small children
Your device and its accessories may contain small parts. Keep
them out of the reach of small children.
Operating environment
This device meets RF exposure guidelines when used either
in the normal use position against the ear or when positioned
at least 1.5 centimetres (5/8 inch) away from the body. When
a carry case, belt clip, or holder is used for body-worn
operation, it should not contain metal and should position
the device the above-stated distance from your body.
To transmit data files or messages, this device requires a
quality connection to the network. In some cases,
transmission of data files or messages may be delayed until
such a connection is available. Ensure the above separation
distance instructions are followed until the transmission is
completed.
Medical devices
Operation of any radio transmitting equipment, including
wireless phones, may interfere with the functionality of
inadequately protected medical devices. Consult a physician
or the manufacturer of the medical device to determine if
they are adequately shielded from external RF energy or if
you have any questions. Switch off your device in health care
facilities when any regulations posted in these areas instruct
you to do so. Hospitals or health care facilities may be using
equipment that could be sensitive to external RF energy.
Implanted medical devices
Manufacturers of medical devices recommend that a
minimum separation of 15.3 centimetres (6 inches) should be
maintained between a wireless device and an implanted
medical device, such as a pacemaker or implanted
cardioverter defibrillator, to avoid potential interference
with the medical device. Persons who have such devices
should:
•
Always keep the wireless device more than 15.3
centimetres (6 inches) from the medical device when
the wireless device is turned on.
•
Not carry the wireless device in a breast pocket.
