Modifications are, therefore, inevitable and specifications are subject to
change without notice or obligation to retrofit. Should any discrepancy
appear to exist, please contact the distributor's Service Division.
WARNING: Static discharges can destroy expensive components.
Discharge any static electricity your body may have
accumulated by grounding yourself to the ground buss in
the unit (heavy gauge black wires connect to this buss).
IMPORTANT: Turn the unit OFF during disassembly and part
replacement. Recheck all work before you apply power
to the unit.

■TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked s
and must be replaced with parts having specifications equal
to those originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
●Meter impedance should be equivalent to 1500 ohm shunted
by 0.15µF.
■INTERNAL VIEW
“CAUTION”
“F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 4A, 125V FUSE.”
CAUTION
F1: REPLACE WITH SAME TYPE 4A, 125V FUSE.
ATTENTION
F1: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 4A, 125V.
WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and /or plastic
(where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency
(and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-
SON WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before
handling food.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both polarities.

●設定
1）リアパネルにある主電源スイッチをOFFにします。
2）動作確認時間を短縮するため、MAINP.C.B.（3）にある
R252の両端に10kΩの抵抗を取り付けます。
3）信号発生器の出力信号を本機の入力2端子に接続しま
す。
4）信号発生器を正弦波、100Hz、8mVに設定します。
5）リアパネルにある主電源スイッチをONにします。
●確認
1）オートスタンバイ／感度スイッチを「低」に合わせます。
2）STANDBY/ONスイッチをONにします。
表示LEDが点灯（緑色）します。5〜10秒後、表示LEDが
赤色に変わります。
3）STANDBY/ONスイッチをOFFにします。
表示LEDが消灯します。
4）オートスタンバイ／感度スイッチを「高」に合わせます。
5）STANDBY/ONスイッチをONにします。
表示LEDが点灯（緑色）します。時間が経過しても表示
LEDの色は変化しません。
6）STANDBY/ONスイッチをOFFにします。
表示LEDが消灯します。
●確認終了後
1）リアパネルにある主電源スイッチをOFFにします。
2）R252両端に取り付けた抵抗を外します。
Setting
1) Turn off the power switch located on the rear panel.
2) In order to shorten the time required for operation
check; connect a 10 kΩresistor at both ends of R252
on the MAIN P.C.B. (3).
3) Connect the output signal from the signal generator to
the L / MONO terminal of the unit.
4) Set the signal generator for the sine wave of 100 Hz, 8
mV.
5) Turn on the power switch located on the rear panel.
Confirmation
1) Set the AUTO STANDBY switch to the LOW position.
2) Turn on the STANDBY/ON switch.
The display LED lights up (green) and its color changes
to red after 5 to 10 seconds.
3) Turn off the STANDBY/ON switch.
The display LED goes off.
4) Set the AUTO STANDBY switch to the HIGH position.
5) Turn on the STANDBY/ON switch.
The display LED lights up (green) and its color remains
unchanged even after time have elapsed.
6) Turn off the STANDBY/ON switch.
The display LED goes off.
After Confirmation
1) Turn off the power switch located on the rear panel.
2) Disconnect the 10 kΩresistor connected to both ends
of R252.
