• Safety Precaution (This "Safety Precaution" is applied only inU.S.A.)
1.Before servicing,unplug the power cordto prevent an electric shock.
2. When replacing pads, use only maanufaacturer's recomended components for safety.
3. Check the COnditionof 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 tothe customer,be sure to make the following insulationresistancetest to prevent the customer from
being exposed to a shock hazard.
• INSULATION RESISTANCE TEST
1. Unplugthe power cord and short the two prongs of the plug witha jumper wire.
2. Turn on the power switch.
3. Measure the resistance value withohmmeter between the jumpered AC plug and each exposed metal cabinet pad, such as screwheads antenna,
control shafts, handle brakets, etc. Equipmentwithantenna terminals shouldread between 3 MQ and 5.2 MQ to all exposed pads. (Fig.A)
Equipment withoutantenna terminalsshould 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 isoutside the specified limits, there is a possibilityof a shock hazard. The equipment should be repaired and rechecked before
it isreturned to the customer.
