How do you switch from c to f ?
To switch from celsius to fahrenheit, the Safety 1st Quick Read Ear Thermometer must be in the "off" position. Then press and hold the "scan" button until a selection appears for celsius and fahrenheit. When the button is blinking the setting you wish, release the scan button.
I have tried to switch from C TO F with no results and I an not happy. It was working in F for 2 weeks and automatically switched to C. When I went to return it to the store they wanted to give me store credit and I would like my money returned to me please.
