Press the on/off button next to the LCD display. A beep will sound when the display turns on and will show the last recorded temperature. Then the thermometer is ready for use.
Place the baby thermometer in the mouth. Make sure the mouth is closed and breathe evenly through the nose to avoid the measurement being influenced by inhaled/exhaled air. Normal temperature between 35.7°C and 37.3°C (96.3°F and 99.1°F).
The degree sign flashes throughout the measurement process. When the flashing stops, the alarm will sound for approximately 10 seconds. The temperature will be displayed on the LCD simultaneously. The displayed temperature will not change when the thermometer is removed from the child's mouth.
To prolong battery life, press the on/off button to turn the unit off after completing the test. If no action is taken, the unit will automatically turn off after about 10 minutes.
* Note: If the measured temperature is lower than 32°C or 90°F, the LCD will display "Lo", if the measured temperature is higher than 42.9°C or 109.9°F, the LCD will display "Hi".
