Have a Auber 2342 that occasionally shows what looks like A (space) (space) 1 on the lower display. A in the left most position, 1 in the right most position.
Don't seem to see this in the manual nor did a quick online search seem to reveal anything.
Just sent an email to Auber, but wondering if anyone here has seen it and or knows what it means.
Oh, and the key pad doesn't seem to do anything when that A 1 shows up. If I unplug it and plug it back in it's fine again for a while. Doesn't seem to be any pattern I can put my finger on at present.
