13、 there is some special features you should be aware of. 1. In order to power up, the Master Unit and Socket Unit needs to be connected thru the interface cable, do to the main SMPS is placed in the Socket Unit, along with the RGB Video processor and microprocessor. 2. Right before signals from the M

14、aster Unit and Socket Unit goes into the interface cable, they are converted into current signals. If you need to measure the signals going in and out the interface cable, you need to measure before or after the converters. 3. All SMPSs in the Master Unit is synchronized along with the SMPSs in the

15、Socket Unit. But the main SMPS in the Socket Unit is only synchronized, along with the rest, when the BeoCenter 2 is receiving AM signal in RADIO mode. If the synchronizing isnt working, it can create a lot of noise in the AM reception. 4. The DVD/CD are not able to start up when the keyboards are o

16、pen or dismantled, doing to exposure of the laser pickup. A little magnet should be used to activate the hall sensor. Disconnect the BeoCenter 2 from the mains, place the magnet and then connect the BeoCenter 2 to the mains again. After start up, the magnet can be removed, and the hall sensor will s

17、till detect the keyboards as closed, which give full functionality with the keyboards open/detached, until load is pressed. See page : 6.17 5. If measurements need to be done on the outlet plugs on the Socket Panel, remember to use the GND in the same plug you are about to measure in. The GND level

18、can vary from plug to plug. 6. All data communication to the DVD interface is done with signal levels on 3.3 volts, if this level vary, it can cause data failure. 7. The VFD display has an auto contrast function, if this fail, the light in the display can vary from very bright to almost black. 8. Th

19、e interface cable between the Master Unit and the Socket Unit is very sensitive to sharp bends or any other large mechanical influence. Damage can result in poor sound/picture quality or fault in the data communication between the Master Unit and Socket Unit. 9. If one of the two IR-modules fails, t

20、he IR sensitivity will be reduced. 10.All analogue audio processing is done in the analogue Audio engine (module 50). The digital SPDIF signal is not going through any processing, beside it is DC levelled on module 01. Service tips, English 5.1 Service Menu There are two ways to enter the service me

The errors in NVMEM are stored permanently, and can be

24、 used if BC2 has been disconnected from mains after an error has occurred. The VMEM only stores errors that have occurred after BC2 has been connected to the mains. 5.2 Service menu, English .NVMEM 1 4F 00000002 10/11/02 2 08 16000000 9/11/02 3 4F 00000002 8/11/02 4 08 16000000 7/11/02 5 4F 00000002
