2. Before Repairs

1. Turn off the power supply. Using a10 , 10 Wresistor, connect

both ends of power supplycapacitors (C703, C704) inorder to

discharge the voltage.

2. Before turning the power supplyon, after completion of repair,

slowlyapplythe primaryvoltage byusing apower supplyvoltage

controller to make sure that the consumed current at 50 HzinNO

SIGNALmode shouldbe shownbelow with respectto supply

voltage 230/240 V.

3. Protection Circuitry

The protection circuitrymayhave operatedif eitherof the following conditions is noticed:

-Nosound isheard when the power isswitched ON.

-Sound stops during aperformance.

The functions of this circuitryis toprevent circuitrydamage if, forexample, the positive and

negative speakerconnection wires are shorted, orif speakersystems withanimpedance less

thanthe indicatedratedimpedance of this unit are used.

If this occurs, followthe procedures outlinedbelow.

1. Switch OFF the power.

2. Determine the cause of the problem and correct it.

3. Switch ONthe power once again.

Note:

When the protection circuitryfunctions, the unitwill not operate

unless the power isfirst switched OFF and then ONagain.
