Hi Jonas !
i guess that the AN1x runs some kind of self test "program" when you 
power up the synth, it's very common (because it's useful and quite easy 
to do) on \ufffdPs based electronics. If it "sees something wrong" in the RAM 
maybe it could go wrong, hang up.... what's puzzling me is that you get 
no error message, but who knows ? The "lo bat" warning appears at the 
very end of the self test, after "welcome to AN1x ..." , so check your 
battery once again.
To be completely sure you can check the connectors , unplug and plug 
them carefully but firmly. Most of the electronics connectors are 
"foolproof" so you cannot plug them in a wrong way. Troubles with 
connectors are common, dusty or rusty pins or bad contact because of a 
loose connector. If they are clean, firmly and completely plugged in 
their socket they should be OK for a long time. This includes the 
battery socket : check it and clean it carefully (alcohool + cotton tip) 
if necessary.
Good luck !
Cheers.
