4. Operating Instructions

4.1. Power On/Off

• To power on, press the Scan Button (power icon). The device will perform a self-test and display the last measurement.
• The device features an automatic power-off function after 30 seconds of inactivity to conserve battery life.

4.2. Taking a Measurement

The thermometer uses contactless infrared technology. For accurate readings, ensure the measuring distance is between 0-3 cm from the target.

1. Point the temperature sensor towards the forehead (for body temperature) or the object surface (for object temperature).
2. Ensure the distance is within 0-3 cm.
3. Press the Scan Button once.
4. The temperature reading will be displayed on the LCD within approximately one second.

Figure 4.1: Temperature indication with 3-color backlit display. This image illustrates how the LCD backlight changes color based on the measured body temperature range: Green for normal (32.0°C - 37.5°C), Yellow for elevated (37.6°C - 38.0°C), and Red for high (38.1°C - 42.9°C). It also shows examples of object temperature measurement.

Temperature Indication (Body Mode):

• Green Backlight: 32.0°C - 37.5°C (Normal)
• Yellow Backlight: 37.6°C - 38.0°C (Elevated)
• Red Backlight: 38.1°C - 42.9°C (High)

4.3. Switching Measurement Modes (Body/Object)

The thermometer can measure both body temperature and object surface temperature. Refer to the manual for specific instructions on how to switch between these modes using the Setting Button.

4.4. Unit Conversion (°C/°F)

To switch between Celsius (°C) and Fahrenheit (°F):

• With the device powered on, press and hold the Setting Button (often labeled 'SET' or similar) until the unit changes on the display.

Figure 4.2: Comparison of Celsius (°C) and Fahrenheit (°F) temperature displays. This image shows the thermometer displaying a body temperature reading in both Celsius (36.2°C) and Fahrenheit (97.1°F).

4.5. Memory Function

The thermometer can store up to 20 sets of past measurements.

• To access memory, press the Memory Button (often indicated by three dots or a memory icon).
• Press the Memory Button repeatedly to cycle through stored readings.

4.6. Adjusting Backlight and Sound

You can toggle the backlight and sound (buzzer) functions:

• Press and hold the Setting Button (often labeled 'SET') to enter settings mode.
• Use the Scan Button to cycle through options (e.g., F2 for Backlight on/off, F3 for Sound on/off).
• Press the Setting Button again to confirm your selection or exit settings.

5. Maintenance and Care

• Cleaning: Wipe the thermometer clean with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
• Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. The recommended storage environment is (-20.0°C to 55.0°C) with relative humidity ≤93%.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display. Remove batteries if the device will not be used for an extended period.

6. Troubleshooting

If you encounter issues with your thermometer, please consider the following:

• No Power: Check if batteries are inserted correctly and have sufficient charge. Replace with new AAA batteries if necessary.
• Inaccurate Readings: Ensure the measuring distance is correct (0-3 cm). Avoid taking measurements in environments with strong electromagnetic interference or extreme temperature fluctuations. Allow the thermometer to acclimate to room temperature for 30 minutes before use if it has been stored in a very hot or cold environment.
• Display Errors: If an error code appears, refer to the full product manual or contact customer support for assistance.
