5. Operating Instructions
The thermometer provides accurate readings in approximately 10 seconds. Ensure the probe is clean before use.
Taking a Temperature Reading:
- Turn on the thermometer by pressing the power button.
- Place the probe according to the desired measurement method (oral, rectal, or axillary).
- Hold the thermometer in place until the beeper alarm sounds, indicating the measurement is complete.
- Read the temperature displayed on the LCD screen.
- Press the power button again to turn off the thermometer, or it will automatically shut off after approximately 10 minutes of inactivity.
Measurement Methods:
- Oral Use: Place the probe tip under the tongue. Close your mouth and hold the thermometer in place. Normal oral temperature is typically 96.3℉-99.2℉ (35.7℃-37.3℃).
- Rectal Use: This method is generally recommended for infants and young children. Gently insert the probe tip into the rectum. Normal rectal temperature is typically 96.3℉-99.2℉ (35.7℃-37.3℃).
- Axillary (Underarm) Use: Place the probe tip in the armpit, ensuring good skin contact. Hold the arm firmly against the body. Normal underarm temperature is typically 95.4℉-98.6℉ (35.2℃-37.0℃).

Battery Replacement:
The thermometer requires 1 LR41 battery. When the battery is low, a battery symbol will appear in the lower right corner of the LCD display. To replace the battery, carefully remove the battery cap and insert a new LR41 battery, ensuring correct polarity.

Storage:
Store the thermometer in its provided storage case in a cool, dry place, away from direct sunlight and extreme temperatures.
7. Troubleshooting
- "Lo" Display: If the display shows "Lo℉" (or "Lo℃") after turning on, it indicates that the thermometer is ready for measurement and the ambient temperature is below the measurable range. This does not mean the battery is low.
- Inaccurate Readings: Ensure the probe is clean and properly positioned for the chosen measurement method. Avoid touching the probe with hands or hot objects before measurement. If issues persist, try replacing the battery.
- No Display/Not Turning On: Check if the battery is correctly installed or needs replacement.
