Hi Beoworld, I need to replace the backup battery in my Beomaster 7000 and can't find the complete procedure. I even downloaded the service manual from the forum (which I believe isn't complete), but it doesn't explain anything about it. Can anyone help me please ?

Thanks

Hi pepps, I haven't seen this thread, but I've seen others, and none of them have answered my questions. I'd prefer a complete service manual for the BM 7000 for a complete description. The only one I've been able to find is for the BM 6500, which I think is slightly different...

The Service Manual on the site should be enough to go on - it shows the position of PCB4 (page 10-1), and a diagram of PCB4 (page 11-5 - two versions shown) showing where the battery is located.

I usually fit these batteries as the have the correct pin spacing:

The BM6500 should also have some overall dismantling instruction which will be similar if not identical to BM7000.

Further to the above, this video may be useful:  https://www.youtube.com/watch?v=zVLcn-fd3VY

You can see the removal of PCB4 about 10 minutes in - the battery will be under the metal cover with the yellow label.

Sometime the Kose videos can be a bit 'rough and ready' (I would never use a powered screwdriver, for instance), so just be very careful not to break anything else when dismantling, especially when disconnecting plugs and prising old brittle plastic out of the way.

EDIT:  See also this thread for a picture of the battery:

Hi Guy, thanks for the information (I'd already seen some of it). I was thinking of doing what you suggested. I don't think I haven't any trouble to disassemble the BM 7000 and replacing the battery. My doubt is about the correct procedure for restoring the factory settings. I can probably use the BM 6500 settings as a reference. Or I could connect another battery in parallel before unsoldering the original one so as not to lose the programming.
