Charging The Battery
Before using the phone for the first time, do not
forget to charge the battery. You can charge
the phone with a travel adapter or by simply
connecting the device to a PC with a USB cable.
Use only OBI/OBI approved chargers

or cables can cause batteries to
explode and can damage your
phone.
We suggest you charge the battery
for 4 hours continuously at least for
the first time.
