19、 REQ?”, press “OK” button. For CE version, the 9K/10KHz switch should be set to 9KHz and the voltage should be 230V AC. For UL version, the 9K/10KHz switch should be set to 10KHz and the voltage should be 115V AC. The 4/8 ohm switch should be set in 4ohm position in all version. Ground-SW: GROUND.4.
20、 Upgrade MCU software The software of main CPU P89C669 can be upgraded via RS232. The programming steps are as follows: Connect the AVP700 to the computer. On AVP700, press the buttons RDS INFO and STORE at the same time. Then the front panel should display Program Req.:. Then press OK button. Or yo
21、u can press RDS INFO and STORE for 3 seconds. Front panel will then display Program. The AVP700 is ready to be programmed. Note: when the program process is stopped unexpectedly, the program in IC may be erased. You can press these two buttons for 3 seconds for programming. Run the AVP700test.exe an
