11、Specifications and external appearance are subject to change without notice as a result of product improvement. RadioFans.CN 收音机爱 好者资料库 R-801A SERVICE PROCEDURES 4. Memory Preservation This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the cont

12、ents 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 placement of the unit. On the av erage, memory contents are p

13、rotected 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. 2. To initialize the unit This device employs a microprocessor to perform various functions and operations. If interference generated by a

14、n 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 MEMORY button, then press the DISPLAY button. 2. Press the

15、 STANDBY/ON button. 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. Safety-check out (120V model only) After correcting the original service problem, perform the following safety check before

16、 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. 1. Replacing the fuses This symbol located near the fuses indicates that the fuse used is fast operating type. For co

17、ntinued 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.
