Mains voltage

A main voltage of 115V and 230V can be chosen. Please check
whether the mains voltage used corresponds with the volta-
ge indicated by the mains voltage selector on the rear panel.
If not, the voltage has to be changed. In this case the line fuse

Changing the line fuse

The fuses are accessible from the outside and contained in
the line voltage connector housing. Before changing a fuse
disconnect the instrument from the line, the line cord must
be removed. Check fuse holder and line cord for any damages.
Use a screw driver to loosen the fuse holder screw counter-
clockwise while pressing the top of the fuse holder down. The
top holding the fuse will then come off. Exchange the defective
fuse against a correct new one.
It is forbidden to repair defective fuses or to bridge them by any
means. Any damage caused this way will void the warranty.
