2、component video Cb voltage to 550mV30mV. 6 Turn RV805 to adjust the component video Cr voltage to 600mV30mV. - 9 - AVR250 SURROUND SOUND RECEIVER IMPORTANT NOTES 1. 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

3、 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

4、 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 AVR250 to the computer. On AVR250, press the buttons RDS INFO and STORE at

5、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 AVR250 is ready to be programmed. Note: when the program process is stopped unexpectedly, the program in IC may be era

6、sed. You can press these two buttons for 3 seconds for programming. Run the AVR250test.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 show
