Hi, Gary

I suppose you have the source level program, so

What I usually do for R/C devices :

One jumper allows a programming sequence when placed before power up; if not, "normal " program starts :

1) program 1 st position ( a couple of pushbuttons for + and - trimming are fine)

2) take jumper off to valid setting and place it back.

2) program 2 nd position

3) take jumper definitly off

The program then stores settings into the EEPROM and enters "its "normal" running.
