Default HPI 71451 temp gun

I have an HPI 74151 temp gun and i have lost the instructions. Somehow it has switched to reading centigrade. How do I switch it back to farenheit?

Press the mode button(the little one), and choose "temp" mode via the bigger one, then you can set it.

Default Any luck with the temps gun's manual?

Hi i got a temp gun from a friend with no manual either. did you find one you could share?

I am getting a "Hi" on the screen but nothing else works when i press the main button.
the mode button shows min. max, lock and the Hi stays on all time : ((

Any tips would be welcomed!
