• To ensure proper installation, use the supplied
parts in the manner specified. If any parts other
than the supplied ones are used, they may damage
internal parts of the amplifier, or they may
become loose causing the amplifier to shut down.
• Never replace the fuse with one of greater value
or rating than the original fuse. Use of an improp-
er fuse could result in overheating and smoke and
could cause damage to the product and injury
including burns.
