We live in a home built in 1999 that has multi-room audio. Today, out of the blue, the in-ceiling speakers in the dining room began to announce in fairly frequent intervals "Please charge battery now." The volume remains the same even if I try to reduce it (which generally I can do from nob in the room.) The speakers are not currently connected to any source. I do not know the brand. We have a 12' high ceiling which adds to the challenge of understanding the problem.
Anyone out there know of speakers that might do this? and have tips on charging the battery? (?)
