The TD-1261 Forehead Thermometer is a non-contact infrared thermometer designed for measuring human body temperature. It is suitable for use by individuals at home, as well as by medical professionals or in environments where a thermometer is needed. The device utilizes infrared technology to measure temperature, making it a convenient and hygienic option as it does not require physical contact.
Function Description
The thermometer measures the infrared heat generated by the surface of the skin over the temporal artery. This method provides an accurate and reliable temperature reading. The device can store up to 10 recent readings in its memory, allowing users to track temperature changes over time. It also features Bluetooth connectivity, enabling it to transmit data to a mobile device via a dedicated app. This allows for easy tracking, storage, and sharing of temperature data. The app can also be used to change the temperature unit (Celsius or Fahrenheit) and set up multiple user profiles.

Usage Features
The TD-1261 is designed for ease of use. To take a measurement, simply press the On/Memory button to turn on the thermometer, then hold the Scan button and aim the probe cover at the center of the forehead, within 3 cm. Release the Scan button to read the result. The device will beep twice to indicate a successful measurement. The display will show the temperature reading, along with a smiley face icon if the temperature is within the normal range, or a frowning face icon if it is elevated. The backlight will turn red for temperatures above 100.4°F (38°C).
The thermometer automatically turns off after 3 minutes of inactivity to conserve battery life. It is recommended to wait at least 3 minutes between measurements to ensure accuracy.
The LCD screen displays various indicators:
- Temperature reading
- Temperature unit (Fahrenheit or Celsius)
- Memory symbol
- Memory number
- Low battery indicator
- Bluetooth indicator
- Scan symbol
- Skin/Surface temperature indicator
Bluetooth Connectivity:
To transmit data via Bluetooth, ensure the thermometer is on and Bluetooth is enabled on your mobile device. Open the app, and the thermometer will automatically connect. The app allows for:
- Changing temperature units.
- Setting up multiple user profiles.
- Viewing and storing measurement data.
- Sharing data with healthcare providers.
Troubleshooting:
The manual provides solutions for common error messages such as "Err.1" (temperature is below or above the measurement range), "Err.2" (system error), "Err.4" (battery is low), and "Err.5" (Bluetooth connection error).
Maintenance Features
- Cleaning: The thermometer body can be wiped clean with a soft, dry cloth. The probe cover and lens should be cleaned with a cotton swab or soft cloth moistened with 70% isopropyl alcohol. Do not use abrasive cleaners, thinners, or benzene. Do not immerse the device in water or any other liquid.
- Storage: Store the thermometer in a cool and dry place, away from direct sunlight, extreme temperatures, and humidity.
- Battery Replacement: When the low battery indicator appears, replace the two AAA alkaline batteries. Ensure the batteries are inserted with the correct polarity.
- General Care: Avoid dropping the thermometer or subjecting it to strong impacts. Keep it away from strong electromagnetic fields. Do not attempt to modify or repair the device yourself.
Important Safety Instructions:
- Always keep the thermometer out of reach of children and pets.
- Do not use the thermometer for purposes other than measuring human body temperature.
- Consult a physician if you have a fever or other symptoms of illness.
- Do not use the thermometer if it is damaged or has suffered damage.
- Avoid direct sunlight and exposure to extreme temperatures.
- Do not use the thermometer near strong electromagnetic fields.
- Do not dispose of the device in household waste; follow local regulations for electronic waste disposal.
