Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of soldering iron around 270˚C

during repairing.

• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering

or unsoldering.

ELECTRICAL ADJUSTMENTS

Bias Adjustment

1. Rotate the semi-fixed resistors (RV501, RV601) for bias

adjustment to the MIN side fully (counterclockwise direc-

tion).

2. Connect a digital voltmeter to CN501 (TP) and CN601

(TP).

1P : ’side, 2P : ‘side

3. Turn ON the power button, and adjust RV501 and RV601

sothatthedigital voltmeterdisplay becomes22 mV± 2mV

within 5 seconds.

4. After the adjustment, turn OFF the power button.
