Nokia lumia 820 Guia Do Utilizador

Nokia understands how important it is that your mobile phone or device operates reliably and that your personal content is saved

safely.
Any information from an unknown or unreliable source, for example, via Bluetooth connectivity, multimedia message, or cable,

may harm your PC, mobile phone, or device. You may protect your mobile phone or device from damage and keep it secured by

following simple measures:
•

Always keep Bluetooth connectivity closed unless you want your phone or device to be visible to others, when your phone

or device supports Bluetooth.

•

Always be alert when receiving information, like Bluetooth file or multimedia message, from an unknown or untrustworthy

source.

•

Always download and install applications or content, like ringing tone or game, from trusted or well-known sources, such as

Nokia Store, where good protection is provided against viruses and other harmful software.

This is a friendly reminder, the mentioned function may vary from different device model.

This device meets radio frequency exposure guidelines in the normal use position at the ear or at least 1.5 centimetres (5/8

inch) away from the body. Any carry case, belt clip, or holder for body-worn operation should not contain metal and should

position the device the above-stated distance from your body.
The sending of data files or messages requires a quality network connection and may be delayed until such a connection is

available. Follow the separation distance instructions until the sending is completed.
Parts of the device are magnetic. Metallic materials may be attracted to the device. Do not place credit cards or other magnetic

storage media near the device, because information stored on them may be erased.

Radio signals may affect improperly installed or inadequately shielded electronic systems in vehicles. For more info, check with

the manufacturer of your vehicle or its equipment.
Only qualified personnel should install the device in a vehicle. Faulty installation may be dangerous and invalidate your warranty.

Check regularly that all wireless device equipment in your vehicle is mounted and operating properly. Do not store or carry

flammable or explosive materials in the same compartment as the device, its parts, or accessories. Do not place your device or

accessories in the air bag deployment area.

Switch your device off in potentially explosive environments, such as near petrol pumps. Sparks may cause an explosion or fire

resulting in injury or death. Note restrictions in areas with fuel; chemical plants; or where blasting operations are in progress.

Areas with a potentially explosive environment may not be clearly marked. These usually are areas where you are advised to

switch your engine off, below deck on boats, chemical transfer or storage facilities, and where the air contains chemicals or

particles. Check with the manufacturers of vehicles using liquefied petroleum gas (such as propane or butane) if this device can

be safely used in their vicinity.

This mobile device meets guidelines for exposure to radio waves.
Your mobile device is a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves

recommended by international guidelines. These guidelines were developed by the independent scientific organisation ICNIRP

and include safety margins designed to assure the protection of all persons, regardless of age and health.
The exposure guidelines for mobile devices employ a unit of measurement known as the Specific Absorption Rate or SAR. The

SAR limit stated in the ICNIRP guidelines is 2.0 watts/kilogram (W/kg) averaged over 10 grams of tissue. Tests for SAR are

conducted using standard operating positions with the device transmitting at its highest certified power level in all tested

frequency bands. The actual SAR level of an operating device can be below the maximum value because the device is designed

to use only the power required to reach the network. That amount changes depending on a number of factors such as how close

you are to a network base station.
