When the device or keypad is locked, calls may be possible to the official emergency number

■ Antenna locations
Your device has four antennas: cellular antenna, Bluetooth antenna, WLAN
antenna, and GPS antenna. The antennas are integrated, and located at the
upper and lower parts of your device.
Note: Your device may have internal antennas. As with any radio
transmitting device, avoid touching the antenna area unnecessarily while the
antenna is transmitting or receiving. Contact with such an antenna affects the
communication quality and may cause the device to operate at a higher power level
than otherwise needed and may reduce the battery life.
■ Connect a compatible headset
Do not connect products that create an output signal as this may
cause damage to the device. Do not connect any voltage source to
the universal headset connector.
When connecting any external device or any headset, other than
those approved by Nokia for use with this device, to the universal
headset connector, pay special attention to volume levels.
■ Connect a USB data cable
To set the default USB connection mode, select Menu >
Settings > Data Cbl. > Data Cable Mode and the desired
mode. To set the default mode to be activated automatically,
select Ask on connection > No.
