Use this switch to select the appropriate system input voltage according to the voltage supply in your area. If the voltage supply in your area is 100-127V, set the switch to 115V. If the voltage supply in your area is 200-240V, set the switch to 230V. Setting the switch to 115V in a 230V environment or 230V in a 115V environment will seriously damage the system! ASUS BM2220 1-3
