Hello, I'm looking to change the pressure setting on my GoodKnight 418. This is my spare unit which is approximately 14 years old and I need to bump up the setting.
I did email and receive the manual from the board. Unfortunately the only manuals for the 418 where for the 418A and 418P. My model is just the plain 418.
I did find the secret button, however, I can't figure out the necessary steps to change the setting.
Any help would be appreciated.
WELCOME! to the forum.!
Hang in there for suggestions, someone will be along to help, soon.
Best of luck to you.
