five minutes have passed.
2. Open the control box cover after turning OFF the power without fail. Then, changing over the supply
voltage.
This product uses a power transformer for changing over the voltage.
If you want to change over the supply voltage, change over the voltages of both of the MC-702 electrical
box and the electrical box of the AW-3 device.
