• Install  the  unit  only  in  a  location  that  can
structurally  support  the  weight  of  the  unit  and  the
mounting  bracket.  Doing  otherwise  may  result  in
the  unit  falling  down  and  causing  personal  injury
and/or property damage.
• Since  the  unit  is  designed  for  in-door  use,  do  not
install it outdoors. If installed outdoors, the aging of
parts causes the unit to fall off, resulting in personal
injury.  Also,  when  it  gets  wet  with  rain,  there  is  a
danger of electric shock. 
Indicates  a  potentially  hazardous  situation
which,  if  mishandled,  could  result  in  moderate
or  minor  personal  injury,  and/or  property
damage.
CAUTION
• Avoid  touching  the  unit's  sharp  metal  edge  to
prevent injury.
• To avoid electric shocks, be sure to  switch off  the
amplifier's power when connecting speakers.
• Do  not  operate  the  unit  for  an  extended  period  of
time with the sound distorting. This is an indication
of  a  malfunction,  which  in  turn  can  cause  heat  to
generate and result in a fire.
