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 me

21、mory 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. Connect the insulatin

22、g-resistance tester between the plug of power supply cord and screw on the back panel. Specifications: 3.3Mohm10% at 500V. 4. Memory Preservation This unit does not require memory preservation batteries. A built-in memory power back-up system preserv es the contents of the memory during power failur

23、es 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 over a period of a few weeks a

24、fter the last time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid climate. 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 befo

25、re plugging in the unit. 1. Determine the proper voltage for your area: 220-230 V or 120 V. 2. If the preset voltage is not correct for your area, insert a screw- driver into the groove in the switch. Slide the switch all the way to the right (120 V) or to the left (220-230 V), which ever is appropr
