1. Prepare a DC power supply which output voltage can be adjusted from 5V to 8V
(output current must be larger than 0.5A). Power off the indicator and unplug the
AC adaptor.
2. Connect the DC power to battery connector on main board. Adjust the voltage
to about 6V
3. Turn on the indicator with the [ON/OFF] key.
