5.2 Replacing the Fuse

WARNING

• To avoid electric shock, always turn off the POWER

switch and unplug the power cord from an outlet before
replacing the fuse.

• Make sure that the replacement fuse is of the correct

shape, and rating for mater specifications. Never use a
fuse having a different rating; never short-circuit the
fuse holder.

1. Turn off the POWER switch and unplug the power cord from the

outlet.

2. Disconnect the power cord from the AC inlet on the rear panel.
3. Use a screwdriver to remove the fuse holder, as shown in Fig.

5.1.
