Use the battery and charger for their intended purposes only. Improper use of, or use of unapproved or incompatible, batteries or chargers may present a risk of fire, explosion, or other hazards, and may invalidate any approval or warranty. If you believe the battery or charger is damaged, take it to a service centre or your local phone shop before continuing to use it. Never use a damaged battery or charger. Only use the charger indoors. Do not charge your device during a lightning storm. When charger is not included in the sales pack, charge your device using the data cable (included) and a USB power adaptor (may be sold separately). You can charge your device with third-party cables and power adaptors that are compliant with USB 2.0 or later and with applicable country regulations and international and regional safety standards. Other adaptors may not meet applicable safety standards, and charging with such adaptors could pose a risk of property loss or personal injury.
To unplug a charger or an accessory, hold and pull the plug, not the cord.
Additionally, the following applies if your device has a removable battery:

• Always switch the device off and unplug the charger before removing the battery.
• Accidental short-circuiting can happen when a metallic object touches the metal strips on the battery. This may damage the battery or the other object.

SMALL CHILDREN
Your device and its accessories are not toys. They may contain small parts. Keep them out of the reach of small children.
MEDICAL DEVICES
Operation of radio transmitting equipment, including wireless phones, may interfere with the function of inadequately shielded medical devices. Consult a physician or the medical device’s manufacturer to determine if it is adequately shielded from external radio energy.

IMPLANTED MEDICAL DEVICES

To avoid potential interference, manufacturers of implanted medical devices (such as cardiac pacemakers, insulin pumps and neurostimulators) recommend a minimum separation of 15.3 centimetres (6 inches) between a wireless device and the medical device. Persons who have such devices should:

• Always keep the wireless device more than 6 inches (15.3 centimetres) from the medical device.
• Not carry the wireless device in a breast pocket.
• Hold the wireless device to the earopposite the medical device.
• Switch the wireless device off if there is any reason to suspect that interference is taking place.
• Follow the manufacturer’s directions for the implanted medical device.

If you have any questions about using your wireless device with an implanted medical device, consult your health care provider.
HEARING
Warning: When you use the headset, your ability to hear outside sounds may be affected. Do not use the headset where it can endanger your safety.
Some wireless devices may interfere with some hearing aids.
PROTECT YOUR DEVICE FROM HARMFUL CONTENT
Your device may be exposed to viruses and other harmful content. Take the following precautions:

• Be cautious when opening messages.
  They may contain malicious software or otherwise be harmful to your device or computer.

• Be cautious when accepting connectivity requests, browsing the internet, or downloading content. Do not accept Bluetooth connections from sources you do not trust.

• Only install and use services and software from sources that you trust and that offer adequate security and protection.

• Install antivirus and other security software on your device and any connected computer. Only use one antivirus app at a time. Using more may affect performance and operation of the device and/or computer.

• If you access preinstalled bookmarks and links to third-party internet sites, take the appropriate precautions. HMD Global does not endorse or assume liability for such sites.

VEHICLES
Radio signals may affect improperly installed or inadequately shielded electronic systems in vehicles. For more information, check with the manufacturer of your vehicle or its equipment. Only authorised 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.
POTENTIALLY EXPLOSIVE ENVIRONMENTS
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 are usually 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.

CERTIFICATION INFORMATION (SAR)

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 (radio frequency electromagnetic fields), recommended by international guidelines from the independent scientific organisation ICNIRP. These guidelines incorporate substantial safety margins that are intended to assure the protection of all persons regardless of age and health. The exposure guidelines are based on the Specific Absorption Rate (SAR), which is an expression of the amount of radio frequency (RF) power deposited in the head or body when the device is transmitting. The ICNIRP SAR limit for mobile devices is 2.0 W/kg averaged over 10 grams of tissue. SAR tests are carried out with the device in standard operating positions, transmitting at its highest certified power level, in all its frequency bands.
Please refer to www.nokia.com/phones/sar for the maximum SAR value of the device.
This device meets RF exposure guidelines when used against the head or when positioned at least ⅝ inches (1.5 centimetres) away from the body. When the device is kept in a carry case, belt clip, or other form of device holder during use, the holder should not contain metal and should provide at least the above-stated separation distance from the body.
To send data or messages, a good connection to the network is needed. Sending may be delayed until such a connection is available. Follow the separation distance instructions until sending is finished.
During general use, the SAR values are usually well below the values stated above. This is because, for purposes of system efficiency and to minimise interference on the network, the operating power of your mobile is automatically decreased when full power is not needed for the call. The lower the power output, the lower the SAR value.
Device models may have different versions and more than one value. Component and design changes may occur over time and some changes could affect SAR values.
For more information, go to www.sar-tick.com. Note that mobile devices may be transmitting even if you are not making a voice call.
The World Health Organisation (WHO) has stated that current scientific information does not indicate the need for any special precautions when using mobile devices. If you are interested in reducing your exposure, they recommend you limit your usage or use a handsfree kit to keep the device away from your head and body. For more information and explanations and discussions on RF exposure, go to the WHO website at www.who.int/healthtopics /electromagnetic-fields#tab=tab_1.
