PROBLEM POSSIBLE CAUSE REMEDY
If a fault occurs, run through the table below before taking your amplifier for repair.
If the fault persists, attempt to solve it by switching the amplifier off and on again. If this fails to resolve the situation, consult
your dealer. Under no circumstances should you repair the amplifier yourself as this could invalidate the warranty.
