11、ialize the unit This device employs a microprocessor to perform various functions and operations. If interference generated by an external power supply, radio wave, or other electrical source results in accident which causes the specified operations and functions to operate abnormally. To perform a

12、result, please follow the procedure below. 1.Press and hold down the VIDEO-1 button, then press the STANDBY button. 2.After Clear is displayed, the preset memory and each mode stored in the memory, such as surround, are initialized and will return to the factory setting. 4. Changing the AM band step

13、 With the exception of the worldwide models, a tuning step selector switch is not provided. When you change the band step, change the parts as shown below. To 10kHz To 9kHz R714 Open 10 k 3. Safety-check out (U.S.A. model only) After correcting the original service problem, perform the following saf

14、ety check before releasing the set to the customer. Leakage Current Check Measure leakage current to a known earth ground(water pipe, conduit, etc.) by connecting a leakage current tester between the earth ground and exposed metal parts of the appliance (input/output terminals, screwheads,metal over

15、lays, etc.).
