Show the software version Press “DVD” and “SAT” at the same time.2. Light up all the icon on the VFL Press “CD” and “TAPE” at the same time.3. Reset Press “FM MUTE” and “PRESET/TUNE” at the same time. When VFL shows “Resetl1 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. Upgrade MCU software The software of main CPU P89C669 can be upgraded via RS232. The programming steps are as follows: Connect the AVR300 to the computer. On AVR300, press the buttons RDS INFO and STORE at the same time. Then the front panel should display Program Req.:. Then press OK button. Or you can press RDS INFO and STORE for 3 seconds. Front panel will then display Program. The AVR300 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 AVR300test.exe and click the button Program to CPU. Select the appropriate COM Port and click the “Browse” to load the hex file. Then click the button Program. Upon the upgrade process is completed, a pop window will be shown. Note: Please try it again if there is error response. AVR350 SURROUND SOUND RECEIVER- 10 -5. Upgrade DSP softwareDSP code in Flash Rom AT29LV040A can be upgraded via RS232. Connect the AVR300 to the computer. On AVR300, press the buttons RDS INFO and FM Mute/Mono at the same time. Then the front panel should display Program Req.:. Then press OK button. Or you can press RDS INFO and FM Mute/Mono for 3 sec-onds. Front panel will then display Program. The AVR300 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 AVR300test.exe and click the button Program to DSP. Select the appropriate COM Port and click the “Browse” to load the s28 file. Then click the button Program. Upon the upgrade process is completed, a pop window will be shown. Finally, use Dolby, DTS, PCM test discs to see if all decodings are ok. This ensure the DSP has been upgraded successfully.
