Antenna

Note: Your device may have internal and external antennas. As with any
radio transmitting device, avoid touching the antenna unnecessarily when the
antenna is in use. Contact with such an antenna affects the communication
quality, may cause the device to operate at a higher power level than otherwise
needed and may reduce the battery life.
The picture shows the antenna area marked in grey.

Headset

Warning: Listen to music at a moderate level. Continuous exposure to high
volume may damage your hearing.
When connecting any external device or any headset, other than those approved by
Nokia for use with this device, to the Nokia AV Connector, pay special attention to volume
levels.
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.
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 Nokia AV Connector.
