3. About the Protection Circuitry
Theprotection circuitrymay have operatedifeitherofthefollowing conditionsis
noticed:
*Nosound isheard whenthepowerissupplied.
*Sound stopsduring aperformance.
Thefunctionsofthiscircuitryistopreventcircuitrydamage, for example, the
positive and negative speakerconnection wires are“shorted”, or ifspeaker
systemswithanimpedandeless thantheindicatedratedimpedance ofthisunit
areused.
Ifthisoccurs, followtheprocedureoutlinedbelow:

1. Press theSTANDBY /ONbutton, switchtoSTANDBY mode.
2. Determinethecause oftheproblemand correct it.
3. Press theSTANDBY /ONbutton once again, supplythepower.
Note:
Whentheprotection circuitryfunctions, theunitwill notoperate unless the
STANDBY /ONbutton isfirst switchedSTANDBY and thenONagain.
