SAFETY PRECAUTIONSThe following check should be performed for thecontinued protection of the customer and servicetechnician.LEAKAGE CURRENT CHECKMeasure leakage current to a known earth ground(water pipe, conduit, etc.) by connecting a leakagecurrent tester such as Simpson Model 229-2 orequivalent between the earth ground and all exposedmetal parts of the appliance (input/output terminals,screwheads, metal overlays, control shaft, etc.). Plugthe AC line cord of the appliance directly into a 120VAC 60 Hz outlet and turn the AC power switch on. Anycurrent measured must not exceed 0.5 mA.DeviceundertestLeakagecurrenttesterEarthgroundReading shouldnot be above0.5 mAAlso test withplug reversed(Using AC adapterplug as required)Test allexposed metalsurfacesAC Leakage TestRadioFans.CN 收音机爱 好者资料库 SX-315356785678CDFABEImportant Check Points for Good ServicingIn this manual, procedures that must be performed during repairs are marked with the below symbol.Please be sure to confirm and follow these procedures.1.
