The power supply voltage setting of the 6243/44 can be switched manually.
The following explain the procedures for changing the power supply voltage setting, checking the fuse and
replacing the fuse.
NOTE:
1.
If the power fuse blows it may cause abnormalities in the operation of the 6243/44. Contact ADC CORPORA-

The available settings (100 V, 120 V, 220 V and 240 V) are imprinted on the volt-
age selector.
