voltage.Thereare2kindsofinputACvoltageselectableaccording to the switch label
110V and 220V. 110V is for input AC voltage 115VAC and 220V is for input AC voltage
230VAC. Attention: wrong AC voltage input will damage the SDA‐2. Once power cable is
connected,turnonthepowerswitchandyouwillseethepowerindicatorturnedon.
