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 displayed, the preset memory and each mode stored in the memory, such as surr

17、ound, are initialized and will return to the factory setting. 3. Safety-check out (U.S.A. model only) After correcting the original service problem, perform the following safety check before releasing the set to the customer. Leakage Current Check Measure leakage current to a known earth ground(wate

18、r 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 overlays, etc.). Plug the power supply cord directly into a 120V AC 60 Hz outlet and turn Standby switch on. Any current meausred

19、must not exceed 0.5mA. 1. 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 type fuse. For fuse rating refer to the marking adjacent to the symbol. Ce symbole indique que le fusi

20、ble utlise est a rapide. Pour une protection permanente, nuntiliser que fusibles de meme type. Ce darnier est la qu le present symbol est appse. 4.Setting the voltage selector (Worldwide models only) Worldwide models are equipped with a voltage selector to conform with local power supplies. Be sure

21、to set this switch to match the voltage of the power supply in your area before plugging in the unit. Determine the proper voltage for your area: 220-230 V or 120 V. If the preset voltage is not correct for your area, insert a screwdriver into the groove in the switch. Slide the switch all the way t
