trolled by the 2 digit or 4 digit address. To switch to the 2 digit
address, program a value of 006/x06 into CV29.

service mode programming.

system is temporarily busy and you will have to try the task again
until you get a “Good” response.
If you get a “Fail” message in response to any programming task, check
to be sure that there is a loco on the programming track and that the
programming track is powered.
