Check the condition of the power cord. Replace if wear or damage is evident.

After servicing, be sure to restore the lead dress, insulation barriers, insulation papers,
sheilds. etc.

Before returning the serviced equipment to the customer, be sure to make the following
insulation resistance test to prevent the customer from being exposed to a shock hazard.

INSULATION RESISTANCE TEST (For U.S.A.)

1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2,
3. Measure the resistance value with ohmmeter between the jumpered AC plug and each

Turn on the power switch.

exposed metal cabinet part, such as screwheads, antenna, control shafts, handle
brackets, etc. Equipment with antenna terminals should read between 3M9 and 5.2MQ to
all exposed parts'. (Fig. 1) Equipment without antenna terminals should read
approximately infinity to all exposed parts. (Fig. 2)

t Note: Some exposed parts may be isolated from the chassis by design, These will read

infinity,

It the measurement is outside the specified limits, there is a possibility of a shock hazard.
The equipment should be repaired and rechecked before it is returned to the customer.
