Tip: You can use USB charging when a wall outlet is not available. Data can be transferred while
charging the device. The efficiency of USB charging power varies significantly, and it may take a long
time for charging to start and the device to start functioning.
Make sure your computer is switched on.
First connect the USB cable to the computer, then to your phone. When the battery is full, first disconnect
the USB cable from your phone, then from the computer.
The battery can be charged and discharged hundreds of times, but it will eventually wear out. When the
talk and standby times are noticeably shorter than normal, replace the battery.
Connect the Headset
Enjoy your favorite music, or free your hands for other things when in a call.
The headset may be sold separately.
■ Connect the headset to your phone.
Do not connect to products that create an output signal, as this may damage the device. Do not connect
any voltage source to the audio connector. If you connect an external device or headset, other than those
approved for use with this device, to the audio connector, pay special attention to volume levels.
Antenna Locations
Learn where the antennas are located on your phone to get the best possible performance.
Avoid touching the antenna area while the antenna is in use. Contact with antennas affects the
communication quality and may reduce battery life due to higher power level during operation.
