Voltage selection card with pin
❏ Remove the fuse holder to gain access to the voltage selec-
tion card. Pull out the voltage selection card horizontally, using
a small pair of pliers to hold it at the white pin.
❏ Four operating voltages are printed on the voltage selection
card and labeled accordingly. Take the pin out and position it
in the recess, so that it is on one line with the correct operat-
ing voltage (see Figure 8-4).
