If interference generated by an external power supply, radio wave, or other electrical source results in accident which causes the specifi

18、ed operations and functions to operate abnormally. To perform a result, please follow the procedure below. 1.Press the STANDBY ON button to turn on the unit. 2.Press and hold down the VIDEO 1 button, then press the STANDBY/ON button. 3.After CLEAR is displayed, the preset memory and each mode stored

19、 in the memory, such as surround, are initialized and will return to the factory setting. 4.Unplug the power supply cord. 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 in

20、sulating-resistance tester between the plug of power supply cord and screw on the back panel. Specifications: 3.3Mohm+/-10% at 500V. 4. Memory Preservation This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of the memory during pow

21、er 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 over a period of a fe

22、w weeks after the last time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid climate.

The initial setting is9 kHz, and this needs only to be changed if you are using the TX-SR800 in a 10-kHz region. 5.Setting the voltage selector (Worl

24、dwide models only) Worldwide models are equipped with a voltage selector so that you supplies. Be can set your TX-SR800 to conform with local power sure to set this switch to match the voltage of your area before plugging in the unit. Determine the proper voltage for your area: 220-230 V or the pres

25、et voltage is not correct for your area, into the groove in the switch and slide (220-230 V), whichever is appropriate.
