How do I change a safety 1st baby monitor from celsius to Fahrenheit?

Answer:
I was seaching for an answer, and I was able to change it using a method similar to the thermometer answer. First I hit the + button and held it while I then pressed the power button. It just switched from C back to F. I'm not sure how it changed to C in the first place!!! But I must have hit the same combo at some point! (Model 08320)
