If excessive ac mains input current is detected, an internal fuse will blow. This can occur for a variety of reasons, such as internal failure, excessive ac mains voltage, or excessive amplifier output levels. If the fuse blows, have a technician replace it with the identical type of fuse.

In the unlikely event the fuse blows again, internal failure is indicated, requiring troubleshooting and repair by a qualified service technician. Do not attempt further use of the loudspeaker until such repairs are made.
