Replacing the fuses This symbol located near the fuses indicates that the fuse used is fast operating type. For continued protection against fire hazard, replace with same

14、 type fuse. For fuse rating refer to the marking adjacent to the symbol. Ce symbole indique que le fusible utlise est a rapide. Pour une protection permanente, nuntiliser que fusibles de meme type. Ce darnier est la qu le present symbol est appse. CIRCUIT NO. PART NO. DESCRIPTION 2. To initialize th

15、e 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 result, p

16、lease 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 as surround, are initialized and will return to the

17、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 tester between the plug of power supply cord and scre

18、w 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 when the unit is unplugged. The unit must be plugged

19、 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 time the unit has been unplugged. This period is s

20、horter when the unit is exposed to a highly humid climate.
