2.1.1 Battery Charging
This device contains a rechargeable Li-Polymer battery. First-time charging time is about 4 hours. Later-on
recharging time is around 2-3 hours. Detailed charging procedures are as follows:
1. Plug the connector of the charger to handsfree’s charging port.
2. Connect the car charger to the cigarette lighter to start charging. Both the Red and Blue LEDs will be on during
charging. Once the Red LED turns off, the battery is fully charged and you should disconnect the charger from
the handsfree and the power outlet.

You can also use the USB charging cable to charge the device on your PC, which will take longer to charge as the
power output of the USB port is lower than it is with the car charger.
Note:

2. Please note that “inserting” charger will cause a device reset and power off. The existing connection between
the device and the mobile phone will be disconnected.
