5.2. Replacing the Fuse
DANGER!
The Thorlabs SA201 Spectrum Analyzer Controller must be powered off,
unplugged from the AC input source, and disconnected from any piezo
elements prior to replacing the fuse or removal of the cover. Failure to do so
may cause SERIOUS INJURY to the user, since high voltages exist within the
unit.
