I have just changed the battery due to a bF code being displayed. Now the system will not reset and the DAY led stays off even though I have not activated the system.
I had one of those yesterday. Not a customer of mine and when I powered up it showed 'rr' (engineer reset required) so I had to reprogramme the bloody thing.
