[Help with Kennedy Box Mod, DIsplay always says off.]

It does have a dna 250 I checked. And I've looked through all that information but I cant find even a screen that says off. I even changed the theme using escribe hoping it would change but alas nothing. I've been trying to upload a picture of the screen but the upload on this site seems to not work. SO i did this:

[Help with Kennedy Box Mod, DIsplay always says off.]

I recently picked up a Kennedy box mod and was searching for instructions but this mod is almost non existent according to the internet. I have figured out how to change the modes and adjust the watts but whenever I am in TC mode the screen simply says off, all while the mod still works. I am just trying to figure out what is going on and how to change it. If anyone knows how to use or has an instruction manual for a Kennedy I would appreciate the help!
