Intended Use
The Kinsa Smart Ear Thermometer is intended to measure the human body temperature in the ear. This device is reusable for clinical or home use on both adults and children older than 1 year old.

Warnings And Precautions

  • This thermometer uses Bluetooth Low Energy 4.1 to communicate with Apple and Android mobile devices. Please see for the full list of supported devices.
  • Clean the probe before and after use.
  • Never use the thermometer for purposes other than body temperature measurement. Please follow the safety precautions when using on children.
  • The operating ambient temperature range for this thermometer is 60.8 – 104 °F (16 – 40 °C).
  • Do not expose the thermometer to temperature extremes: (below -13 °F / -25 °C or over 131 °F / 55 °C) or excessive humidity (>95% RH). Use of this thermometer is not intended as a substitute for consultation with your physician.
  • High, prolonged fever requires medical attention. Be sure to contact your physician.
  • The thermometer is water resistant, not waterproof. Never dip the thermometer into water or other liquids. Do not boil the probe. For cleaning and disinfecting, please see Cleaning and Storage.
  • Keep out of reach of unattended children. Do not allow children to walk or run while taking a temperature.
  • Do not store the unit in direct sunlight or at high temperatures.
  • Kinsa recommends using a password on your smartphone to protect your information
  • WARNING Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to SmartEar. Otherwise, degradation of the performance of this equipment could result.
  • WARNING: Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in improper operation. If such use is necessary, this equipment and the other equipment should be observed to verify that they are operating normally.
  • Power line magnetic fields (in excess of 3A/m) should be kept at a distance to reduce the likelihood of interference. Warning keep DEVICE away from sources of high levels of power line magnetic fields (in excess of 30 A/m) to reduce the likelihood of interference
  • Do not mix alkaline, standard or rechargeable batteries.
  • Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this device.

Body Temperature
Temperature readings vary from person to person, by age, time of day, and by site of measurement. For example, core body temperature often decreases with age. The best method to determine your own normal temperature is to use the thermometer when you are feeling well. Record your temperature twice a day (early morning and late afternoon) using the Kinsa app. Take the average of the two temperatures. This is considered your normal body temperature. Any variation from it may indicate some sort of illness and you should consult your physician.

Why Measure in the Ear?
Ear temperatures accurately reflect core body temperature, since the eardrum shares a blood supply with the temperature control center in the brain: the hypothalamus.1 The Kinsa Smart Ear Thermometer monitors the infrared heat radiated from the eardrum and surrounding tissue and detects once an accurate temperature measurement has been taken.

To Set Up Your Thermometer For First Time Use

To Set Up Your Thermometer

Open the battery door E.

Insert two AAA batteries (included), making sure the poles are in the right direction, into the thermometer. Snap battery door into place.

Enable Bluetooth on your mobile device.

Download the Kinsa app from the App Store or Google Play. The app can also be downloaded by going directly to Please see for the full list of supported devices.

Launch the Kinsa app. (The app will be on your Home screen or in your Apps folder depending on type of mobile device.)

Turn the thermometer on and follow the prompts to install.

Your thermometer is now successfully connected to your mobile device. For future temperature readings, open the Kinsa app to automatically sync readings to your mobile device and assign to individual family members, add notes or symptoms/medications, and see guidance.

Having trouble?

Your thermometer will display APP until it is connected with the Kinsa app. If your thermometer won’t connect to the app, you can activate it on its own by turning it on and pressing the big white button 2 times in rapid succession. Note: viewing temperature history or receiving guidance will not be possible until the thermometer has been connected to the app. For additional support, contact Customer Happiness at

To Set Up Your Thermometer with Additional Mobile Devices

  1. If you have the original phone, open Kinsa, go to “More,” select the thermometer to remove and choose “Forget Thermometer.”
  2. On the additional mobile device, repeat Steps 3 through 7 above.
  3. Your thermometer is now successfully connected to an additional mobile device.

Taking a Temperature

1.Tap the Power/Start button A to turn on the thermometer. You will hear a
beep when the thermometer is ready to take a temperature.

During an internal self-check, the display shows all segments. The thermometer will be ready for temperature taking when the screen shows three dashes.


2. First, gently tug the ear straight up and back. Next, fit the probe snuggly into the ear canal. Be sure to position the probe so that it is pointing toward the center of the head. Once in position, push and release the Power/Start button.

3. A beep will indicate when the temperature measurement is successfully
completed. Temperature readings typically take 1 second.

4. The temperature reading will be shown on the illuminated display. A smiling face icon indicates that the temperature is normal while a neutral or frowning face indicates a mild or high fever, respectively.

5. The thermometer will automatically turn off after 30 seconds of inactivity. The display will briefly flash OFF and it will go blank. You can also hold down the button to power off.

NOTE: Always take measurements in the same ear since temperature readings may
differ from the right and left ear.

Kinsa recommends taking your temperature three times in the same ear and using the
highest of those readings. This is especially important if you meet the following criteria:

  1. Children under three with a compromised immune system
  2. Individuals unfamiliar with this thermometer

Changing The Temperature Scale
If you wish to change the temperature scale of your thermometer, turn your
thermometer on and then press the big white button two more times in rapid

NOTE: temperature scale in app can be changed within app settings

Replacing the Battery
The Kinsa Smart Ear thermometer is powered by 2 AAA batteries. The low battery
icon displays when power is low. To protect the environment dispose of empty
batteries at appropriate collection sites according to national or local regulations.
Keep out of reach of young children, elderly, and pets. To replace the batteries:

  1. Open the back battery cover by pressing on the Kinsa logo and applying
    downward pressure to slide it off.
  2. Remove the old batteries and replace with new ones. Make sure the the batteries
    are in the correct polarity direction.
  3. Close the battery cover.

Cleaning And Storage

To ensure your Smart Ear thermometer is recording accurate temperatures, it is very important to keep the probe sensor tip clean. To clean the probe tip, gently wipe it with a cotton swab or soft cloth moistened with alcohol. Gently circle the alcohol wipe around the inner sensor area at the tip of the Smart Ear. Be sure to clean the inner flat surface of the sensor – not just the rim. Never submerge your Kinsa or put it in boiling water or a dishwasher.

Cleaning And Storage

Keep the protective cap snapped onto the top of the thermometer when not in use to
protect the tip from damage.

This thermometer is initially calibrated at the time of manufacture. If this thermometer
is used according to the use instructions, periodic re-adjustment is not required. If at
any time you question the accuracy of temperature measurements, please contact
Customer Support.
