I have an old B&O phone Wall Holder with A/V volume controls that I use as a remote for volume from my kitchen. I cannot work out what phone it used to fit but I find it very useful. It seems to have gone dead and I'm wondering if it has a battery inside. I presume it does but cannot find the compartment. Is anyone able to shed light on this? It is from 1991 and is type 10037949.

Any help would be appreciated.

A photo would help...

My guess would be a Beocom 1400???

Could this help?

edit:

saw now that min wall base link was type no 1003729, not the same as yours -  but this might help anyway.....
