10、s 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 procedur

11、e below. 1.Press and hold down the TAPE 1 button, then press the DIRECT TUNING button. 2.After CLEAR is displayed, the preset memory stored in the memory, are initialized and will return to the factory setting. 3. Safety-check out (Only U.S.A. model) After correcting the original service problem, pe

12、rform the following safety check before releasing the set to the customer. Connect the insulating-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.

13、 A built-in memory power back-up system preserv es the contents of the memory during power 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 pl

14、acement of the unit. On the average, memory contents are protected over a period of a few weeks after the last time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid climate. RadioFans.CN 收音机爱 好者资料库 TX-8011 EXPLODED VIEW TX-8011 A201 A202 P711 P102 Q522 Q
