5. Operating Instructions
5.1 Taking a Forehead Temperature Measurement:
- Ensure the thermometer is clean and the sensor is unobstructed.
- Point the thermometer at the center of the forehead from a distance of 3-5 cm (1.2-2 inches).
- Press the Measurement Button once.
- The temperature reading will be displayed on the LCD screen within 1 second.
- The device will automatically power off after 30 seconds of inactivity to conserve battery life.
5.2 Switching Temperature Units (Celsius/Fahrenheit):
With the thermometer powered on, press and hold the Memory/Mode Button for a few seconds until the unit changes from °C to °F or vice versa. The selected unit will be saved for future measurements.
5.3 Recalling Memory Records:
The thermometer can store up to 9 measurement records. To recall them:
- With the thermometer powered on, briefly press the Memory/Mode Button.
- Each press will cycle through the stored readings, from the most recent to the oldest.
5.4 Backlight Color Indications:
The LCD backlight changes color to indicate different temperature ranges:
- Green Backlight: Indicates a normal temperature range (34.0°C - 37.2°C).
- Orange Backlight: Indicates a medium temperature range (37.2°C - 38.2°C).
- Red Backlight: Indicates a high or low temperature (above 42.2°C or below 34.0°C). This also serves as a fever alarm.
6. Maintenance
Cleaning the Thermometer:
- Use a soft, dry cloth to clean the body of the thermometer.
- For the sensor lens, gently wipe with a cotton swab slightly moistened with alcohol. Allow it to dry completely before use.
- Do not use abrasive cleaners or immerse the device in water.
Storage:
- Store the thermometer in a cool, dry place, away from direct sunlight and extreme temperatures.
- If the thermometer will not be used for an extended period, remove the batteries to prevent leakage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Device won't turn on | Dead or incorrectly installed batteries. | Replace batteries with new 1.5V AAA alkaline batteries, ensuring correct polarity. |
| Inaccurate readings | Sensor is dirty; measurement distance is incorrect; environmental temperature fluctuations. | Clean the sensor. Ensure correct measurement distance (3-5 cm). Allow the thermometer to acclimatize to room temperature for 30 minutes before use. |
| "Lo" or "Hi" displayed | Temperature is outside the measurable range (34.0°C - 42.2°C). | Ensure the measurement is taken correctly on the forehead. If the reading is genuinely outside this range, seek medical attention. |
