4. Setup
Initial Use: The thermometer comes with a pre-installed battery. Remove the protective plastic film from the display if present.
Power On: Press the ON/OFF button. The display will show "188.8°F" briefly, followed by the last measured temperature, and then "Lo°F" (or "Lo°C"). The "Lo" indicates the thermometer is ready for measurement, not that the battery is low.
Select Temperature Unit (°F/°C): With the thermometer off, press and hold the ON/OFF button for approximately 3 seconds to switch between Fahrenheit (°F) and Celsius (°C). The selected unit will be displayed.

5. Operating Instructions
Ensure the thermometer is clean before each use. Press the ON/OFF button to turn on the device. When "Lo°F" (or "Lo°C") appears, the thermometer is ready for use.
5.1 Oral Measurement
Place the probe tip under the tongue as close as possible to the heat pocket.
