Les,

 

Function 10, 11 and 12 can be quickly accessed by holding shift and pressing one of the three buttons on the bottom row of the handset.

 

For function 13 press OPTION then 3, for function 14 press OPTION then 4 and so on....

 

For function 20 press OPTION twice then 0, for function 21 press OPTION twice then 1 and so on.....

I’m grateful for that guidance but have found the the OPTION then 3 etc action does not activate function 13, but only function 3

any further ideas?   Thanks

Where did you get the decoder from and how old is it.

New Bachmann Dukedog - lovely machine.  Coming back to it after 40 years I have a lot to catch up on

Thanks, Suzie - you are quite right - bit of a track clean and it's working fine - I hadn't realised DCC is so sensitive in that way

While using an NEC Powercab to operate a Bachmann loco wth ESU LokSound decoder I inadvertently ALSO connected the track to a 15v AC current (don't ask).  I wondered why operation was rather hesitant, so then compounded matters by changing the 15v AC connection to 12v DC (still connected to the NEC).  At this point response from the loco was minimum, unsurprisingly, and I realised my mistake(s).

I have tried resetting CV8 to 8   -  sometimes that seems to work, and I get some response from the loco - some of the sounds and just a brief commencement of moving before cutting out again.

Have I damaged it irretrievably?   I'm a newbie to DCC (obviously!)
