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.

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.)
(1)セットをクーラ、扇風機のそばなど風通しの良い場所を避け、通常の使用状態に置きます。セットの周囲温度は
15〜30℃、湿度は常湿とします。
Adjustment
(1) Remove top cover and set VR101, VR102, VR103, VR104, VR105 on Amp. Unit, VR106 on SURR.-BACK ch 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, SURROUND-BACK ch: CP106).
(3) Connect power cord to AC Line, and turn power switch "ON".
(4) Presetting. MASTER VOLUME : "---" counterclockwise ( min.)
MODE : 6CH 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.
(1)上カバーをはずし、パワーアンプ基板のVR101,VR102,VR103,VR104,VR105 及びSurr.Back アンプ基板のVR106 を

(3)電源コードをAC100V （95〜105V の範囲でも可）に接続し、電源スイッチを"ON" にします。
(4)ＯＮ後、次のようにセットします。
●VOLUME （音量調節つまみ）→反時計方向( )に回す、最小の状態にする。
●SPEAKER‑A （スピーカ端子）→無負荷（スピーカ、ダミー抵抗器などを接続しない。）
