19、IRCUIT NO. PART NO. DESCRIPTION 2. To initialize 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 func

20、tions to operate abnormally. To perform a result, please follow the procedure below. 1.Press the STANDBY ON button to turn on the unit. 2.Press and hold down the VIDEO 1 button, then press the STANDBY/ON button. 3.After CLEAR is displayed, the preset memory and each mode stored in the memory, such a

21、s surround, are initialized and will return to the factory setting. 4.Unplug the power supply cord. 3. Safety-check out (Only U.S.A. model) After correcting the original service problem, perform the following safety check before releasing the set to the customer. Connect the insulating-resistance te

22、ster between the plug of power supply cord and screw on the back panel. Specifications: 3.3Mohm+/-10% at 500V. 4. Memory Preservation This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of the memory during power failures and even w

23、hen the unit is unplugged. The unit must be plugged in order to charge the back-up system. The memory preservation period after the unit has been unplugged varies depending on climate and placement of the unit. On the average, memory contents are protected over a period of a few weeks after the last

24、 time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid climate. Note: : 120V model only : Australian model model 5. To confirm the version of microprocessor 1.Press the STANDBY ON button to turn on the unit. 2.Press and hold down the DISPLAY button after

25、 more than 15 sec., then press the STANDBY/ON button. 3.After the versions of main,sub and net microprocessors are displayed on FL tube, the unit returns to the original position.
