2. Safety-check out (North American model only)

Before returning the product to the customer, make leakage current or

resistance measurements to determine that exposed parts are acceptably

insulated from the supply circuit.

Parts marked with the symbol are critical with regard to the risk of fire and

electric shock.Replace only parts recommended by the manufacturer.

ALIGNMENT PROCEDURE

A. DC OFFSET VOLTAGE

The DC OFFSET between OFFSET Test Point and AGND must be within 0+/-20mV.

B. IDLING CURRENT

The idling current in the output stage of the poweramp should be set to 25mA+/-5mA per

pnp-npn transistor pair( This means the mid point voltage is 4mV with down limit of 3mV

and up limit of 5mV). The alignment procedure is: At first, adjust RV103 (Marked as “Idling

Current ADJ” in the drawing below) for a voltage of 4mV +/- 1mV between Test point 1 and

2. Then preheat the unit for 5 minutes, let idling current settled and then readjust to 4mV +/-

1mV.

Pls note: Though the idling current is set as 4mV +/-1mV during the adjustment, due to the

influence of varied ambient temperature and mains voltage etc., the idling current will drift after

some time. During the normal checking of idling current in the service field, it’s acceptable as

long as the voltage is in the range of 3mV—5mV.

C. ISC SENSITIVITY

The ISC sensing voltage can allow 0mV+/-50mV. But, for the alignment process in our

factory, we tighten the limit to 0mV+/-10mV. That is to adjust Pot RV104 (as marked as

“ISC SENS ADJ” in the below drawing) to get a voltage between the “ISC SENSE TEST

POINT” and AGND to be 0mV+/-10mV.
