Operating Instructions
1. Taking a Body Temperature Measurement
- Ensure the thermometer is in Body Mode (usually indicated by an icon on the display, e.g., a person's head). If not, switch modes using the designated button.
- Point the thermometer at the center of the forehead from a distance of approximately 3-5 cm (1.2-2 inches). Ensure there is no hair, sweat, or cosmetics obstructing the area.
- Press the measurement button (trigger) once.
- The temperature reading will be displayed on the screen within one second.
- If a fever is detected, the thermometer may emit an audible alarm or change screen color (if applicable).

- Green: Normal temperature (e.g., 95.5°F - 99.1°F or 35.3°C - 37.3°C)
- Orange: Low fever (e.g., 99.2°F - 100.5°F or 37.4°C - 38.0°C)
- Red: High fever (e.g., 100.6°F - 109.2°F or 38.1°C - 42.9°C)
An audible alarm will also sound when a high fever is detected.
Maintenance
1. Cleaning the Thermometer
- Use a soft, dry cloth to clean the thermometer body.
- For the probe and lens, gently wipe with an alcohol swab or a soft cloth moistened with alcohol. Do not immerse the thermometer in water or any cleaning solution.
- Ensure the thermometer is completely dry before storage or next use.
2. Storage
- Store the thermometer in a cool, dry place, away from direct sunlight, dust, and extreme temperatures.
- Remove batteries if the thermometer will not be used for an extended period to prevent battery leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/Display blank | Batteries are dead or incorrectly installed. | Replace batteries with new AAA batteries, ensuring correct polarity. |
| Inaccurate readings | Incorrect measurement distance, dirty probe/lens, or environmental interference. | Ensure correct distance (3-5 cm), clean the probe/lens, and measure in a stable environment. Allow the thermometer to acclimate to room temperature for 15-20 minutes if moved from a different environment. |
| "Lo" or "Hi" displayed | Temperature is outside the measurable range. | Ensure the thermometer is in the correct mode (Body/Object) and the temperature is within the specified operating range. |
