To switch between modes, press the Forehead/Object Button (person/house icon). The corresponding icon will appear on the LCD display.
4.3 Taking a Measurement
Image: A visual guide demonstrating the three steps to measure temperature: 1. Power on and select mode. 2. Point thermometer 2-3 cm from the forehead and press START. 3. Read the temperature after a short beep.
- Ensure the thermometer is in the desired mode (Forehead or Object).
- Position the thermometer 1-3 cm (0.4-1.2 inches) away from the center of the forehead (for body temperature) or the object/surface.
- Press the START button.
- The measurement will be completed after a short beep, and the temperature reading will be displayed on the LCD screen.

4.4 Switching Temperature Units (°C/°F)
To switch between Celsius (°C) and Fahrenheit (°F):
- Ensure the thermometer is in the OFF state.
- Press and hold the START button for 3-5 seconds.
- The display will show the current unit, and then switch to the other unit. Release the button when the desired unit is displayed.

4.5 Fever Alarm Interpretation
The thermometer's LCD backlight changes color to indicate temperature status:
- Green: Normal body temperature (T ≤ 37.3°C / 99.1°F).
- Orange: Low-grade fever (37.3°C < T < 37.7°C / 99.1°F < T < 99.9°F).
- Red: High fever (T ≥ 37.7°C / 99.9°F).
Image: Illustrates the three-color backlight system for temperature alerts: Green for normal, Orange for elevated, and Red for high temperature, with corresponding temperature ranges.
4.6 Memory Recall
The thermometer automatically stores the last 10 temperature readings with the exact time. To access memory recall:
- Turn on the thermometer.
- Press the Forehead/Object Button (person/house icon) repeatedly to cycle through the stored readings.
- Each press will display the next stored reading, starting from the most recent.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Device won't turn on | Dead batteries, incorrect battery installation. | Replace batteries, ensure correct polarity. |
| Inaccurate readings | Incorrect measurement distance, dirty probe, environmental factors (drafts, direct sunlight), recent activity (eating, exercising). | Ensure 1-3 cm distance, clean probe, measure in stable environment, wait 30 minutes after activity. |
| Display shows 'Lo' or 'Hi' | Temperature is outside the measurable range. | Ensure measurement is within specified operating range (e.g., 32°C-42.9°C for body). |
| Display shows 'Err' | System error or malfunction. | Remove and reinsert batteries. If error persists, contact customer support. |
