I’m puzzled as to change the battery on the A3; I tried opening up the ‘white’ model I have, unscrewed all the screws, and tried prising it open with my tools, but it still doesn’t want to budge, so can some kind person provide instructions as to how I can do both the white and black models, as I’m sure the white model is slightly different than the black one, thanks!
found out that I didn’t have to unscrew all those small screws around the edge of the unit, as the battery compartment is under the thick B&O plastic covering at the front of the unit, so just peel back carefully; hope this helps someone!
