WARNING…
BEFORE REPLACING THE REAR PANEL FUSE, ISOLATE THE UNIT FROM THE SUPPLY.
FAILURE TO ISOLATE THE EQUIPMENT PROPERLY MAY CAUSE A SAFETY HAZARD.

When replacing the power input fuse, always ensure that a fuse of the correct type and rating, is fitted.
Failure to do so results in inadequate protection.
