HELP SECTION
1)  WILL NOT TURN ON
Check the power to the unit.  Check for tripped main circuit breakers, unplugged extension cords
or power-strip switches that may be turned off.  Check the amps circuit breaker on the rear panel.
If the black curved center button is in the out position, push it in to reset.  If the breaker contin-
ues to trip, check your speaker cables and total speaker impedance.  If the amps circuit breaker
will not reset, then the amp will require servicing.
2)  MAINTAINING YOUR EQUIPMENT
Avoid spilling liquids or allowing any other foreign matter inside the unit.  The panel of your unit can
be wiped from time to time with a dry or slightly damp cloth in order to remove dust and bring back
the new look. As with all pro gear, avoid prolonged use in caustic environments (salt air).  When
