when the unit is off, push and hold the 'start' button (button that you push to take the temperature). Hold until you see lines and the reading (C / F). When the lines show up, push the 'start' button again until the desired centigrade reading is displayed, then press the power button.

Safety 1st Ear Thermometer
this instruction manual was very helpful and accurate.Thank you so much.
Also, when you first start the instructions if the (C / F) reading does not appear with the lines proceed and it will still reset your thermometer.
