SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.

Idling Current

Required measurement equipment : DC Voltmeter

Preparation

(1)Avoid direct blow from an air conditioner or an electric fan, and adjust the unit at normal room tempereture 15 °C ~ 30 °C (59 °F ~ 86 °F).

(2)Presetting

●	POWER (Power sourse switch)	→	OFF
●	SPEAKER (Speaker terminal)	→	No load (Do not connect speaker, dummy resistor, etc.)

Adjustment

(1)Remove top cover and set VR101, VR102, VR103, VR104, VR105 on Amp. Unit at full counterclockwise ( ) position.

(2)Connect DC Voltmeter to test points (FRONT-Lch: TP104, FRONT-Rch: TP105, CENTER ch: TP103, SURROUND-Lch: TP101, SURROUND-Rch: TP102).

(3)Connect power cord to AC Line, and turn power switch "ON".

(4) Presetting.	MASTER VOLUME	: "---" counterclockwise ( min.)
	MODE	: 5CH STEREO
	FUNCTION	: CD

(5)Within 2 minutes after the power on, turn VR101 clockwise ( ) to adjust the TEST POINT voltage to 1.5 mV ±0.5 mV DC.

(6)After 10 minutes from the preset above, turn VR101 to set the voltage to 2.5 mV ±0.5 mV DC.

(7)Adjust the Variable Resistors of other channels in the same way.
