Before servicing，unplug the power cord to prevent an electric shock．
When replacing parts，use only manufacturers recommended components for safety．
Check the、condition of the power cord． RepIace if wear or damage ls evident．
After servicing，be sure to restore the Iead dress，insulation barriers，insulation papers，shields，etc．
Before retuming the serviced equlpment to the customer，be sure to make the foowing insulation resistance
test to prevent the customer from being exposed to a shock hazard．
●lNSUIATION RESISTANCE TEST
1．Unplug the powercord and short the two prongs of the plug with ajumperwire．
2．Tum on the power switch．
3．Measure the resistance value with ohmmeter between the jumpered AC plug and each exposed metal cabinet
part，such as screwheads antenna，control shafts，handle brackets，etc． Equipment with antenna terminals
should read between3MΩand5。2MΩto aexposed parts（Fig．A）． Equipment without antenna terminals
should read approximately infinity to all exposed parts（Fig、B）．
Note＝Some exposed parts may be isolated from the chassis by design． These will read infinity．

lf the measurement is outside the specified Iimits，there is a possibility of a shock hazard．
should be repaired and rechecked before it ls retumed to the customer．
