The Basics

This manual contains the instructions necessary to operate the product safely and in accordance with its function and intended use. Observance of this manual is a prerequisite for proper product performance and correct operation and ensures patient and operator safety.

Safety

  • Get medical attention if you have high fever or prolonged fever, especially young children. Read carefully and follow the instructions to ensure accurate temperature measurement.
  • Keep out of reach of unsupervised children.Components may be harmful if swallowed.
  •  This device is designed for oral, rectal, or axillary use only.
  • Please note that temperature measuring are affected by many factors, including strong physical activity before
    the test, drinking hot or cold drinks, and measurement methods.
  •  Avoid taking temperature for 30 minutes after physical exercise, bathing, dining, or drinking hot or cold
    beverages.
  •  Stop using the thermometer if it operates erratically or if the display malfunctions.
  •  Allow the thermometer to warm naturally to room temperature before using. Performance may be
    affected if operated or stored outside stated temperature and humidity ranges or if the patient’s
    temperature is below the ambient (room) temperature.
  • Precision components are used in the construction of this device. Extremes in temperature, humidity, direct sunlight, shock or dust should be avoided.
  • Clean the device with a dry, soft cloth or a cloth dampened with water and a neutral detergent. Never use alcohol, benzene, thinner or other harsh chemicals to clean the device .
  • Measurements may be distorted if the device is used close to television, microwave oven, cellular telephone, X-ray or other devices with strong electrical fields.

Using the thermometer

Charge the Battery
Use the USB cable to charge the product. Connect the USB cable to a USB charger or to the PC. There will be a battery logo flash on the device when charging. When the battery is low, the display screen will display a low power prompt.
Note: The device cannot be used during charging. When charging, you must use a class Ⅱ adapter conforming
to IEC/EN 60601-1, and the output is DC 5V 1A. If it is not followed, there may be a risk of electric shock.
3.2Before Measurement

  1.  Please long press the on key to start the product.
  2.  Display history
    The history record appears on the screen, indicating that the value is the last measured temperature.

Measurement
Note:
Before measuring temperature, please clean the temperature measuring head with rubbing alcohol. Rinse it with cool water. The thermometer supports measuring the temperature of multiple body parts. For infants under 3 months old, it is recommended to measure rectal temperature. Please follow the below instructions.

Measuring oral temperature
  1.  With your mouth open, put the temperature-measuring head under your tongue.
  2. Close your lips gently around the thermometer.
  3. Keep the thermometer under your tongue until the digital thermometer beeps.

Lubricate the probe tip with a water-soluble jelly for easier insertion; do not use petroleum jelly,as it may cause an inaccurate reading. Gently insert the probe tip no more than 1/2 inch into the rectum.

After Measurement
When the buzzer emits a beep sound(Beep-short sound), it indicates that the temperature measurement is finished. The display “°C/℉” stops blinking, and the displayed temperature value is the result of the current body temperature.
Note:
When the temperature measured by the device is lower than 35℃or 95 ℉, the screen will display “LOW” with a beep-long sound. When the temperature measured by the device is higher than 41℃ or 105.8 ℉, the screen will display “HIGH” with a beep-long sound.

  • Turn off the thermometer: press and hold (> 0.5 seconds) to switch the thermometer off.
  •  If no operation is performed for more than 3 minutes, the thermometer will automatically turn off. It is
    recommended to manually turn off the thermometer after the temperature measurement to extend the
    battery life.

Cleaning and Disinfecting

Do not use a corrosive detergent to clean the unit. Clean and disinfect the thermometer before and after each
use.
Cleaning Process

  1.  Wipe the probe with a cloth dipped in a disinfectant solution such as 70% isopropyl (rubbing) alcohol or soap and water.
  2. Rinse off disinfectant residue.

Care and Storage

  •  Do NOT drop or crush; this device is not shockproof.
  •  Do NOT dismantle or modify the device.
  •  Do NOT store the device in an extreme environment with direct sunlight or high temperatures.
  • Store the unit in the protective case while not in use.
