I'm hoping someone can help me. I have 2 Ahlborn Archive modules, plus one at my former church. One of the units needs to have its battery replaced and I'm guessing the other two would be about due, too.
I've done this maintenance in the past, but I can't remember if I changed the battery with the unit powered on.... so I don't lose voicing or presets. Can someone provide some advice as to whether or not this is a good idea.
thanks for your advice!
