How do I switch between Celsius and Fahrenheit on my BBLove AET-R1B1 thermometer?

[TaylorLee]

To change the temperature scale on your BBLove AET-R1B1 Non-Contact Infrared Forehead Digital Thermometer, follow these simple steps: First, make sure the thermometer is turned off. Next, press and hold the "ON/OFF/MEASURE" button for about 8 seconds. This will bring the device into temperature mode. The current temperature unit, either Celsius (°C) or Fahrenheit (°F), will be displayed. Now, release the button and then briefly press the "ON/OFF/MEASURE" button again. Each press will toggle between the Celsius and Fahrenheit options. The thermometer will automatically turn off after about 4 seconds of inactivity, saving your selection, and display the last temperature reading. For visual aids and more detailed instructions, please consult the user manual that came with your BBLove AET-R1B1.
