Fuse Replacement and Voltage Selection
Access to the Model 24C's fuses and voltage selector switch is made by using a
screwdriver to open fuse drawer in the power entry module. A slot is provided above
the voltage selector window for this purpose.
The fuse and voltage selection drawer cannot be opened while the AC power cord is

Voltage selection is performed by rotating the selector cams until the desired voltage
shows through the window shown.
There are two fuses that may be removed by pulling out the fuse modules below the
voltage selector. Fuses are specified according to the AC power line voltage used.
