Question about AT&T 5840 Cordless Phone
I have some handsets I purchased on ebay which I'm trying to get to register to the base at my home. I can't seem to get these to unregister from the 'former' base they hold in memory. Does anyone know how to reset these, can you just take the battery out for a week or two and pray it loses the old Base ID? Thanks.
