Implanted medical devices

To avoid potential interference, manufacturers of implanted medical devices recommend a minimum separation of 15.3

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

Connectivity security

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

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.
