Your best bet is probably to go
through the menu items 1 at a time and see what's in there.
I set my screen to turn off in 1 minute and the system in 30 minutes. Turn the temp alarm up, I think mines at 135 or so. Next make sure your battery mah settings are correct.
From there you can choose what info you want on the home screen, I have ohms and watts shown. You can choose to have the fire button preset for a certain amount of time or manual.
From there it's a matter of settling in and using it for a few days. It's a great product, although I've only had it for 60 days. I have a bunch of other
mods but keep coming back to this one
Good luck and have fun!
