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.
