SERVICE PROCEDURES
4. Memory PreservationThis unit does not require memory preservation batteries. Abuilt-in memory power back-up system preserves the contentsof the memory during power failures and even when the unit isunplugged. The unit must be plugged in order to char ge theback-up system.The memory preservation period after the unit has beenunplugged varies depending on climate and placement of theunit. On the av erage, memory contents are protected over aperiod of a few weeks after the last time the unit has beenunplugged. This period is shorter when the unit is exposed to ahighly humid climate.
2. To initialize the unitThis device employs a microprocessor to perform variousfunctions 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 tooperate abnormally.To perform a result, please follow the procedure below.
1. Press and hold down the MEMORY button, then press theDISPLAY button.2. Press the STANDBY/ON button.After "clear" is displayed, the preset memory and eachmode stored in the memory, such as surround, areinitialized and will return to the factory setting.
3. Safety-check out(120V model only)After correcting the original service problem, perform thefollowing safety check before releasing the set to the customer.Connect the insulating-resistance tester between the plug of powersupply 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 thefuse used is fast operating type. For continued protection againstfire hazard, replace with same type fuse. For fuse rating refer tothe marking adjacent to the symbol.
Ce symbole indique que le fusible utlise est a rapide.Pour une protection permanente, n'untiliser que fusibles dememe type. Ce darnier est la qu le present symbol estappse.
