apparatus, the apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.
15).Under no circumstances should the output terminals of the amplifier be
short-circuited.

servicing other than that contained in the operating instructions unless you
are qualified to do so.
Suggestion #3
Warning: If you suspect that the grounding system in your
home's electrical wiring is causing the hum problem, it is
important that you do not make any changes to the wiring. Only
a licensed electrician should make any changes to household
wiring, and they must be made in full compliance with all local
building, safety and electrical codes.
