Host pairing Clear button:
BT5701 host memory paired with it last slave address code, only to find it after power memory
pairing, the host will gi ve up the memory, re-search for new slaves.
Power Supply:
►Built-in lithium battery: Do not insert MINI USB external power supply, the battery-powered switch to the serial port header
struck the opposite side, you can use the built -in lithium battery.
►MINI USB external power supply: the battery-powered switch to the serial port side of the
power supply (computer USB port or 220V power ad apter available), and external
power adapter from an external power supply work. External power supply, if the battery switches
to the opposite side of
the serial port header, it still consumes internal battery power, but this time both the external power supply to charge the battery.
►The built-in lithium battery: either switches to battery which side, insert MINI USB external power supply, will be for the
built- in lithium battery, the internal charging circuitry to manage charging process to prevent overcharging.
