Memory Preservation This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of the

14、 memory during power failures and even when 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 ove

15、r a period of a few weeks after the last time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid climate. 2. To initialize the unit This device employs a microprocessor to perform various functions and operations. If interference generated by an external p

16、ower supply, radio wave, or other electrical source results in accident which causes the specified operations and functions to operate abnormally. To perform a result, please follow the procedure below. 1.Press and hold down the VIDEO-1 button, then press the STANDBY/ON button. 2.After clear is disp

17、layed, the preset memory and each mode stored in the memory, such as surround, are initialized and will return to the factory setting. 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. C

18、onnect the insulating-resistance tester between the plug of power supply cord and screw on the back panel. Specifications: 3.3Mohm+/-10% at 500V. 1. Replacing the fuses This symbol located near the fuses indicates that the fuse used is fast operating type. For continued protection against fire hazar

19、d, replace with same type fuse. For fuse rating refer to the marking adjacent to the symbol. Ce symbole indique que le fusible utlise est a rapide.
