If you need to connect the device to the power supply using a voltage adapter, be sure
to swap the wires connected to the PCB. Disconnect the unused cord, and instead
connect the connecting cord to the selected power source (battery box or voltage
adapter socket).
ATTENTION: Changing the connection of the wires should be done when the power
supply is disconnected.
