4. Operating Instructions

Power On/Off:

• Press the power button (usually the 'Head' button) to turn the thermometer on.
• The thermometer will automatically shut off after approximately 10 seconds of inactivity to conserve battery life.

Forehead Measurement (Indicative Measurement):

1. Ensure the protective cap is on the thermometer tip.
2. Press and hold the 'Head' button.
3. Gently swipe the thermometer from one temple to the other across the forehead.
4. Release the 'Head' button. The temperature reading will appear on the display within 1-3 seconds.

Ear Measurement (Exact Measurement):

1. Remove the protective cap from the thermometer tip.
2. For adults, gently pull the ear backward and upward to straighten the ear canal. For children, pull the outer ear straight backward.
3. Carefully insert the probe into the ear canal.
4. Press the 'Ear' button. The temperature reading will appear on the display within 1-3 seconds.

Changing Temperature Unit (°F/°C):

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

1. Ensure the thermometer is turned off.
2. Press and hold the 'Ear' button for 7 seconds until the display shows "--°C".
3. Release the 'Ear' button and immediately press it again to toggle between the temperature scales.

Memory Recall:

The thermometer stores the last 20 temperature readings. To access memory recall, press the 'M' button (often integrated with the 'Ear' button or a separate mode button) when the device is on. Repeated presses will cycle through the stored readings.

Color Temperature Indicator:

The display backlight changes color to indicate temperature status:

• Green: Normal temperature.
• Orange: Elevated temperature (pay attention to your body).
• Red: Fever detected.

5. Maintenance

Cleaning:

• After each use, especially for ear measurements, clean the probe with an alcohol swab or a soft cloth moistened with alcohol.
• Ensure the sensor lens is clean and free of debris for accurate readings.
• Wipe the main body of the thermometer with a soft, dry cloth. Do not immerse the device in water.

Storage:

Store the thermometer in its soft storage pouch in a cool, dry place, away from direct sunlight and extreme temperatures.

6. Troubleshooting

• Inaccurate Readings: Ensure the sensor lens is clean. Allow the thermometer to acclimate to room temperature for at least 30 minutes if it has been in a significantly different environment. For ear measurements, ensure the probe is correctly inserted and the ear canal is straightened.
• "LO" or "HI" Display: This indicates a temperature outside the measurable range. Ensure proper contact with the skin (forehead) or ear canal (ear).
• No Display/Device Not Turning On: Check battery installation and replace batteries if necessary.
• Repeated Use: Avoid taking measurements repeatedly within 10 seconds, as this can affect accuracy.
