Ah don’t be discouraged. It’s easy once you’ve done it nothing to it. When you hit the up/down buttons you come to a screen that has # flashing like 00-00 or 00-02 or 05-03. The first set of # is the group the second set is the parameter. You change the number by the up/down buttons. And I believe you hold the enter button till the number stops blinking. So you would scroll to get the numbers to 00-00 hit enter then a number will be blinking either 1 or 0. Change number to 1 then push and hold enter. That parameter is now programmed to 1 not 0. And so on so on. Read the manual acouple times till you understand it. Took me like ten times and they say the teco manual is one of the better ones.
