5. Operating Instructions
5.1. General Measurement Steps
- Ensure the device is in the target measurement mode (Body or Surface).
- Position the thermometer 3-5 cm (1-2 inches) away from the target. For forehead temperature, align it with the center of the forehead.
- Press the measurement key (trigger) to initiate the reading.
- The temperature reading will be displayed on the screen within approximately one second.
- After the measurement is completed, the instrument will shut down in 20 seconds if there is no further operation.

6. Measurement Modes
The Dikang HG03 thermometer supports two primary measurement modes:
- Body Temperature Mode: For measuring human body temperature (forehead).
- Surface/Object Temperature Mode: For measuring the temperature of various surfaces or objects such as milk, food, bath water, or room temperature.
Use the mode selection button (often labeled 'Mode' or 'Body/Surface') to switch between these modes as needed.

7. Backlight and Fever Indication
The thermometer features an intelligent three-color backlight system to provide a visual indication of temperature status:
- Green Backlight: Indicates normal body temperature (typically <37.3 °C).
- Yellow Backlight: Indicates a slight fever (typically 37.3 °C - 38 °C).
- Red Backlight: Indicates a high fever (typically 38.1 °C - 40 °C). This is accompanied by a short beep alarm.

8. Accuracy and Measurement Tips
The Dikang HG03 thermometer provides high accuracy with a measurement deviation of ≤ ± 0.3 degrees Celsius. For optimal accuracy:
- Ensure the measurement distance is consistently 3-5 cm from the target.
- Avoid taking measurements immediately after strenuous activity, bathing, or eating.
- Ensure the forehead is clean and dry, free from hair or sweat, when measuring body temperature.
- Allow the thermometer to acclimate to room temperature for at least 30 minutes if it has been stored in a significantly different environment.

9. Care and Maintenance
Proper care ensures the longevity and accuracy of your thermometer:
- Cleaning: Wipe clean the thermometer body and sensor lens with a soft cloth slightly dampened with alcohol or a mild disinfectant. Do not immerse the device in water or any cleaning solution.
- Storage: Store the thermometer in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display. Dispose of used batteries responsibly.
- Avoid Impact: Do not drop the thermometer or subject it to strong shocks.
10. Troubleshooting
If you encounter issues with your thermometer, consider the following:
- No Display/Device Not Turning On: Check battery installation and ensure batteries are not depleted. Replace if necessary.
- Inaccurate Readings: Ensure correct measurement distance (3-5 cm) and proper mode selection (Body/Surface). Check for obstructions on the forehead (e.g., hair, sweat). Allow the device to acclimate to room temperature.
- Error Message on Display: Refer to the specific error code (if any) in the full product manual or contact customer support for assistance.
If the problem persists, contact customer support for further assistance.
