SHOCK, FIRE HAZARD SERVICE TEST :
CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC
cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product and
controls and chassis bottom.
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and
verified before it is return to the user/customer.
Ref. UL Standard No. 1492.
In case of difficulties, do not hesitate to contact the Technical
Department at above mentioned address.

3. IDLING CURRENT ADJUSTMENT
1. Before switching the power ON, set the master volume
c o n t r o l t o t h e m i n i mu m p o s i t i o n a n d t h e b a l a n c e
volume to the center positions. Also set semi-fixed
resistors R755(L ch) and R756(R ch) on PCB P701 to
the center positions.
2. Each of the cement resistors R767(L ch) and R768(R
ch) on the PCB P701 is provided with three test points.
Connect a digital voltmeter, set for the DC voltage
input, to the test points at the two extremities of the
three test points of R767 or R768.
3. After the setup above, switch the power ON, and adjust
semi-fixed resistors R755(L ch) and R756(R ch) on PCB
P701 according to the digital voltmeter reading. The
target setting value is 10 mV(50 mA) for both the L ch
and R ch.
Please refer to the table below.
