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.

CAUTION IN SERVICING

Initializing AV SURROUND RECEIVER

AV SURROUND RECEIVER initialization should be performed
when the µcom, peripheral parts of µcom, and Digital P.W.B. are
replaced.

1. Switch off the unit.

2. Hold the following SPEAKERS-A button and SPEAKERS-B
button, and switch on the unit.

3. Check that the entire display is flashing with an interval of
about 1 second, and release your fingers from the 2 buttons
and the microprocessor will be initialized.

Note:・If step 3 does not work, start over from step 1.

・ All user settings will be lost and this factory setting will

be recovered when this initialization mode.
So make sure to memorize your setting for restoring
after the initialization.

サービス時の注意事項

AVサラウンドアンプの初期化について

マイコンやマイコン周辺部品、Digital 基板等を交換した場合
は、AV サラウンドアンプの初期化を行って下さい。

1. オン／オフボタンを OFF にします。

2. SPEAKERS-A ボタンと SPEAKERS-B ボタンを同時に押しな
がら、オン／オフボタンを押して ON にします。

3. ディスプレイ表示が約 1秒間隔で点滅するのを確認後、2
つのボタンから指を離します。

＊マイコンが初期化されます。

注意 :・上記 3 の状態にならない場合は、もう一度操作 1 か

らやり直してください。

・初期化を行うとお客様が設定した内容が工場出荷状

態に戻りますので、あらかじめ設定内容を控えてお
き初期化後再設定してください。

ADJUSTMENT

Audio Section

Idling Current

Required measurement equipment: DC Voltmeter

1. Preparation

(1) Avoid direct blow from an air conditioner or an electric

fan, and adjust the unit at normal room temperature 15 °C
~ 30 °C (59 °F ~ 86 °F).

(2) Presetting

• POWER (Power source switch) OFF

• SPEAKER (Speaker terminal) No load
(Do not connect speaker, dummy resistor, etc.)

2. Adjustment

(1) Remove top cover and set VR101, VR102, VR103,

VR104, VR105, on Amp. unit, Unit at fully 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 clock-

wise ( ) 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.
