A power surge may have caused a fuse to blow. To change the fuses:
• Unplug the power cord.
• Locate the panel where the power cord plugs in. The fuse box is on
the right side of that panel.
• Press the release tab and pull the fuse-holder out.
• Pull the broken fuse out.
• Replace the broken fuse with a 1.25-A, 250-V fuse.
CAUTION: Do not use any other kind of fuse to avoid risk of damaging the
instrument or voiding the warranty.
• Replace the fuse holder and push it into the fuse well until the
release tab snaps in place.
• Connect the power cord and turn the instrument on.
If the fuse blows again, a failed component may be causing the
problem.
