Bc-890 Channel Loss - Help

[1SCAN1]

Hi Folks:-
Just wondering if any-one could help or have suggestions about a BC-890 that Ihave. The problem is that everything works well but when I un-plug or disconnect the power I loose all the programmed frequencies . Have to re-program every time there is a power loss. Any help or suggestions appreciated. Thank you
Dave

I'm going to bump this one to the top since I want to know too. There isn't much info about this scanner on the site. Is there a watch battery in this this thing? Volatile memory? Are we stuck leaving this thing plugged in?

My friend just gave me one of these. I've pretty much figured out programming it, but a manual for it or a Pro-2036 would be nice. A how-to for a discriminator tap would be great. That would probably be it's best use.

Well I know the pro 2035 and the 2042 have a battery on the board maybe you could take the case apart and look.

Its the lithium battery inside for sure. You'll have to unsolder the battery. I've done more than 20 of these.
