2.3 Charging the
battery
The Danfoss Bluetooth® gateway is equipped with a high-performance rechargeable battery, so an
external power source is not required. This makes the gateway particularly suitable in mobile applica-
tions.
We recommend charging the battery before using the device for the first time.
To avoid overcharging and faulty operation, always use the battery charger supplied with the gateway.
The time required for full charging is approximately 2 hours.
To charge the battery:
1. Connect the charger to the USB port at the rear of the Bluetooth® gateway
2. Then connect the charger to the wall socket.
3. The status of the charging process is indicated by LED1 (“Charging”) on the gateway, as follows:
Battery status, during charging with the USB power supply:

2.4 Recommendations
1. Keep the gateway fully charged, so it is ready for field work.
2. Keep an USB-cable/charger as a backup in the car just for the case someone forgets to charge the
gateway battery
