Safety check out (U.S.A. model only) After correcting the original service problem, perform the following safety check before releasing the unit to the customer. Leakage current Check Measure the leakage current to a known earth ground (water pipe or conduc
4、t etc.) by connecting a leakage current tester between the earth ground and exposed metal parts of the unit (input/output ground terminals, screw heads or metal overlays etc.). Plug the power supply cord directly into a 120Vac 60Hz wall socket and turn ON/STANDBY button on. Any current measured must
5、 not exceed 0.5mA.3. Memory Backup This model uses a EE-PROM IC in order to retain radio presets and other settings. So, memory contents will be kept eternally with no care.4.
