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 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 displayed, the preset memory and each mode stored in the memory, such as surround, are initialized and will return to the factory setting. 3. Unplug the power supply cord. 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(water 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 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 fusible utlise est a rapide. Pour une protection permanente, n'untiliser 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 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 to the upper (120 V) or to the lower (220-230 V), whichever is appropriate. 5.Setting the AM tuning step frequency (Worldwide models only) CIRCUIT NO. PART NO.

The ini- tial setting is 9 kHz. North America: 10 kHz Other countries: 9 kHz Note: All presets are deleted when you change this setting. To set the AM tuning interval, while holding down the [TUNER] button, press the [MEMORY] button.
