CHARGING
The charger delivered with your FieldBee automatically checks for healthy voltages
of the two cells and only attempts charging if they are within limits.
The battery must be charged prior to using it for the first time because it is delivered
with an energy content as low as possible.
Please, fully charge the battery with the external charger before turning on the Base
Station for the first time and if you are going to use it without external power supply.
It is normal for the battery to become warm during charging.
While using FieldBee app you may check next charger information:
power source : external power, battery;
charger status : full charged, charging, discharging, low battery, error.
* If you see the charger status of the battery is low, please, connect cable for charging.
Please, don’t use battery with the low battery status it will negatively affect antenna's
future work.
voltage ( mV)
If you will see the voltage of your batteries is less than 3,35 mV ( low battery status) -
connect charger.
The voltage more than 3,8 mV is normal power mode. You can work with it while batteries
is not discharged to the low battery status.
