The thermometer requires 2 AAA batteries for operation.
5. Operating Instructions
5.1 Power On/Off
Press the measurement button (trigger) to turn on the thermometer. The device will perform a self-test and display the last measurement. The thermometer will automatically shut down after approximately 60 seconds of inactivity to conserve battery life.
5.2 Selecting Measurement Mode
The thermometer can measure body temperature, object temperature, and ambient room temperature. Use the 'MODE' button (if available, refer to device buttons) to cycle through these modes. The selected mode will be indicated on the LCD display.
5.3 Taking a Measurement
- Ensure the correct measurement mode is selected (e.g., Body mode for human temperature).
- Point the thermometer at the center of the forehead from a distance of 3-5 cm (1.2-2 inches) for body temperature. For object temperature, point at the desired surface.
- Press and release the measurement button (trigger).
- The temperature reading will be displayed on the LCD screen within 1 second. A beep sound will indicate the completion of the measurement (if not muted).

5.4 Switching Temperature Units (°C/°F)
With the device powered on, press the 'SET' button (or similar button indicated on your device) to switch between Celsius (°C) and Fahrenheit (°F). The selected unit will be displayed on the screen.
5.5 Memory Function
The thermometer can store up to 20 previous temperature readings. To access the memory, press the 'MEM' button. Each press will cycle through the stored readings. This feature helps in tracking temperature changes over time.
5.6 Fever Alarm Function
The device is equipped with a fever alarm function. If a body temperature reading exceeds a predefined threshold (e.g., 99.5°F or 37.5°C), the thermometer may emit a specific alarm sound or change the backlight color to indicate a potential fever.

6. Maintenance
6.1 Cleaning
- Use a soft, dry cloth to clean the thermometer body.
- For the probe and lens, gently wipe with a cotton swab slightly moistened with alcohol. Allow to dry completely before use.
- Do not use abrasive cleaners or immerse the device in water.
6.2 Storage
- Store the thermometer in a cool, dry place, away from direct sunlight and extreme temperatures.
- Remove batteries if the device will not be used for an extended period to prevent leakage.
7. Troubleshooting
If you encounter issues with your thermometer, refer to the following common solutions:
- No Power: Check if batteries are inserted correctly and are not depleted. Replace batteries if necessary.
- Inaccurate Readings: Ensure the probe is clean. Make sure the measurement distance is correct (3-5 cm for forehead). Avoid taking measurements in environments with strong airflow or extreme temperature changes. Allow the thermometer to acclimatize to room temperature for 30 minutes if moved from a different environment.
- Error Message on Display: Refer to the specific error code in the full product manual (if available) or contact customer support. Common errors might indicate ambient temperature outside operating range or sensor issues.
- No Beep Sound: Check if the mute function is activated.
