Can anyone help me figure out the problem that I am experiencing with my Beomaster 4500?
1. I usually get a “Code” error showing on the touch glass panel every time I unplugged and plugged in system. I, then, have to perform the 1 2 7 1 Code to have it disappeared.
2. While the system is constantly plugged in to power ,however, and turn it ON, I never get the Code error showing up on the glass panel screen but my previous volume setting + treble, bass & balance settings were not saved. The settings revert back to 0.
Does anyone know the cause of this? Any help would be highly appreciated.

Bad backup battery in processor module.

Thanks Jacob. Is this easy to replace and do you know what kind of battery do I need to replace it with?
Weebyx rather.

It is very easy to change if you have experience in electronics. It is not "user servicable", so it is not intended for the end user to be able to change it.
You need to remove the glass panel(and be carefull, since this will probably come loose, and need to be glued back on), then remove the top cover, and then in the middle, there is at small metal box that holds the processor and battery. I cannot remember the correct battery right now, but it is soldered to the PCB and is not in a socket, so be very careful not to heat it to much, since these batteries can explode when heated.
If you have no experience, then I would not do this my self.

What Weebyx just said.- And get the battery polarity correct right from the start. Lithium batteries should be respected, they go off like a pistol shot and makes a huge mess. - And always remember ESD-protection (tools, workspace and yourself) when working with electronics, - particularly around the processor.It's CMOS technology so quite sensitive.
In some cases the FM frequency readout will have to be aligned after replacing the battery.So will the tonecontrol settings, preset start-up volume and stored FM stations.- But not always.It's all in the servicemanual.First power up after servicing should be without speakers until you have verified (and/or changed) the preset start-up volume setting.
If you are good at electronics and have the servicemanual, the skills and the tools, it's not a big deal.If not, there's a huge risk of doing more damage than good and it would easily be worth the money spent at a good repairer.The new battery is a fairly cheap component and replacing it is a 30-minute job or thereabout so shouldn't be too costly (not counting ifthe glass panel needs refastening - which it will if not already done).

Thanks for all the help and expertise. Highly appreciated.
