Try to go online to search for the manual. On ours there is a button on the back to turn with a coin from celcius to farenheit. Good luck.

My 3 year old son did the same thing to my ear thermometer. It took me a week to get it figured out. Here are the unit instructions: To switch the display between °F and °C, simply turn OFF the unit, press and hold the Activation Button until the ready display appears. Press and release the Activation Button to switch from °F to °C, and vice-versa. Once you have selected a measurement scale wait until the thermometer LCD shows a full display.

Go on to their website. I am sure you can order another set of instructions.

You can do one of two things. Take the batteries out and try to see if that works or you can hold the button down for a few seconds that takes the temperature and it should change back to farenheit.

Good Luck & take care

Google the product name and you may get a website--and the website may have a downloadable manual. I did this with a surround-sound system one of my friends gave me a while back.
