CV settings for stock ESU decoder on Atlas PA1 2nd run

While changing engine numbers on the PA1 I somehow turned off all the CVs for the headlights and number boards. Since I don't have any way to find out what they are and what the settings should be, I wonder if anybody with a LokProgrammer and this loco can tell me . Also, if Atlas Paul is around, maybe I can get the factory settings of which CVs and what they need be set at.

What process did you use to change the loco numbers/address? Will the lights function if you use its original address?

How about a factory reset?  To do a factory reset on an ESU decoder, enter a value of "8" in CV8.  Then remove the engine from power for a few seconds.  Then restart it.  This should get you back to the original factory decoder settings.

Atlas has not made a PA-1 as far as I know.   ConCor, BLI, Kato.  But not Atlas.

Do you mean the FA?

Yes if this is an Atlas loco with factory installed ESU LokSound decoder then writing "8" to CV8 then cutting power to the decoder (lifting the model off the track for few seconds) should restore all the CVs to their original settings (a working configuration). That type of a decoder reset is a feature specific to ESU decoders.

I'm also curious at to what DCC system was used  to change the address and how exactly was it done. I ask because setting address should not modify any other CVs except the three CVs used for long or short address and CV29.

There are way too many CV settings to post here.  This is the LokProgrammer Function mapping for the headlights and the numberboard lights.

I doubt he has a LokProgrammer and besides, that screen shot does nothing to show which CVs are in play.  Plus it appears that OldEastRR is all set. Probably just reset the decoder.
