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 suitable screw driver of appr. 2 mm to depress the
plastic fuse holder releases on both sides, the housing is
marked where the screw driver should be applied. After its
release the fuse holder will come out by itself pushed forward
by springs. The fuses can then be exchanged, please take care
not to bend the contact springs. Reinsertion of the fuse hol-
der is only possible in one position and by pressing against
the springs until the locks engage.
It is forbidden to repair defective fuses or to bridge
them by any means. Any damage caused this way
will void the warranty.
