  The line voltage selector is the fuse holder that contains the fuse. Follow the step above 
to remove the fuse box. 
  The grey colored piece is the fuse holder and the line voltage selector. To change the 
line voltage configuration between 110 V and 220 V, pull this piece out of the fuse box 
and rotate it 180 degrees. 
  Place it back in the fuse box. The front of the fuse box has an opening, which should 
indicate the line voltage you configured. It should display either 110 or 220. If neither 
of these labels is shown in the fuse box opening, pull out the fuse holder and turn it 
again until it shows the line voltage configuration desired.

Any disassembling of the case or changing the fuse not performed by an authorized service 
technician will void the warranty of the instrument.
