Can anyone tell how to change a safety 1st ear thermometer from Celius to Faraheit?
It depends on which model you have. One model says it has a Celsius/Fahrenheit switch, so I’m assuming you don’t have that one. The other 2 models have similar 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. I got this info from their website. http://www.safety1st.com/search.asp click on the model number you have, then look down the left side where it says instruction sheets and click on the model number. Then do “ctrl F” (hold both down at the same time) and search for the word “Celsius” to find it.
