2. Remove PSU cover, held in place by 4 x philips screws.
3. Observe the jumpers located on PCB0718B, and the accompanying diagram
printed on the PCB itself.
4. For 100V: solder jumpers W2, W3, W6
For 120V: solder jumpers W1, W4, W6
For 220/230V: solder jumpers W2, W5
For 240V: solder jumpers W1, W5
Example 1: The board below is set for 120V operation:
Example 2: The board below is set for 220/230V operation:
