Plug the adapter into the RS232 interface of the device that the RS232 Mini Adapter it is to be operated with.
The Bluetooth RS232 Mini Adapter recognises whether or not signals are incoming via the serial interface, i.e.

If the device is switched on, the Bluetooth RS232 Mini Adapter changes into operating mode, LED 2 flashes

battery. (See 2.3)
Please be sure to have the Bluetooth Adapter in use during charging.
2.3. Charging the battery
The Bluetooth RS232 Mini Adapter is equipped with a high-performance rechargeable battery, so an external
power source is not required. This makes the adapter particularly suitable in mobile applications.
We recommend charging the batter before using the device for the first time.
Please notify: connect charger first with BT RS232 adapter and afterwards with wall socket.
To avoid overcharging and faulty operation, always use the battery charger supplied and connect it to the
appropriate socket at the rear of the Bluetooth RS232 Adapter (see Ill.1) .
The status of the charging process is indicated by LED1 on the upper surface of the Bluetooth Adapter (see Ill. 1)
