Voltage Supply Switch Settings

Your IBM Personal Computer might have voltage switches, which must be set correctly for your voltage supply. If your
monitor or system unit has a voltage switch, complete these steps to make sure each switch is set correctly:
1. Determine the correct voltage switch setting for your area:
Voltage Supply Range
100-127 V
200-240 V
2. Locate the voltage switch on the back of your monitor or system unit. If the setting shown on the switch is:
Correct: start setting up your IBM personal computer.
Incorrect: change the voltage switch setting.
Voltage Switch Setting
110 V
220 V
