• Safety Precaution
(This "Safety Precaution" is applied only in U.S.A.)
1. Before servicing,unplug the power cord to prevent an electric shock.
2. When replacing pads, use only maanufaacturer's recomended components for safety.
3. Check the COndition of the power cord. Replace if wear or damage is evident.
4. After servicing, be sure to restore the lead dress,insulationbarriers, insulation papers, shields,etc.
5. Before returning the serviced equipment to the customer,be sure to make the following insulation resistancetest to prevent the customer from
being exposed to a shock hazard.
• INSULATION RESISTANCE TEST
1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with ohmmeter between the jumpered AC plug and each exposed metal cabinet pad, such as screwheads antenna,
control shafts, handle brakets, etc. Equipment with antenna terminals should read between 3 MQ and 5.2 MQ to all exposed pads. (Fig. A)
Equipment without antenna terminals should read approximately infinityto all exposed pads. (Fig. B)
Note: Some exposed pads may be isolated from the chassis by design. These will read infinity.

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