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 www.nokia.com/werecycle, or if browsing on a

mobile device, www.nokia.mobi/werecycle.

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 at www.nokia.com/

environment.

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.
