dangerous. Don't do it!
The fuse is located behind the fuse cover, at the
bottom of the IEC socket. See the "Troubleshooting"
section on page 10 for information about replacing
the fuse.

2. Voltage Selector Switch

Make sure the switch is in the correct position for
your local AC mains voltage before connecting the AC
