Vicks Fever InSight Thermometer illustrated diagram


Thank you for purchasing the Vicks® Fever InSight® Thermometer with a large screen display and Fever InSight® feature, a professional accurate instrument for faster and easier temperature taking.

Please read these instructions carefully to ensure accurate temperature measurements and safe operation. When used properly, this high-quality product will give you years of accurate, dependable service.


  • High, prolonged fever requires medical attention, especially for young children. Please contact your physician.
  • Do not allow children to take their temperatures unattended.
  • Do not allow children to walk or run during temperature taking.
  • The thermometer is only suitable for the measurement of body temperature. The use of this thermometer is not intended as a substitute for consultation with your doctor.
  • The thermometer is initially calibrated at the time of manufacture. If this thermometer is used according to the use instructions, the accuracy of measurements will not be affected.


Temperature readings vary from person to person.

Although there is no one “normal” temperature reading, a temperature, taken orally, ranging between 36.1°C / 97°F and 37.7°C / 100°F is considered normal.

A rectal temperature is generally 0.5°C / 1°F higher and an underarm (axillary) temperature will be 0.5°C / 1°F lower.

The best method to determine your own normal temperature is to use the thermometer when you are feeling well.

Record your reading twice a day (early morning and late afternoon).

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.


Before use warning

Your Vicks® Fever InSight® Thermometer is a 3-in-1 thermometer for oral, rectal, or underarm use. Whichever method is used, it is recommended that for 15 minutes prior to use, you avoid eating or drinking, exercising, taking showers or baths or smoking.



  • Turn the thermometer on by pressing the On/Off button (Fig. 1).
  • A beep signal will sound and the display will flash Red/Yellow/Green for 1 second.
  • Wait for the thermometer to get ready
    – The display will show a test value (Fig. 2).
    – The display will show last measurement for 2 seconds (Fig. 3).
    – After about 5 seconds, the display will show it’s ready (Fig. 4).

Oral Use

  • It is important to place the tip of the thermometer well under the tongue to get a good, accurate reading. (Fig. 5) Place sensor tip in areas marked with “4”. Keep mouth closed and sit still to help ensure an accurate measurement.
  • When the peak temperature is reached (usually within 12 seconds), 5 beep signals will sound and the “°C/°F” sign will stop flashing. The temperature measurement is now ready to read and will not change when the thermometer is removed.
  • Wash the thermometer as recommended.

Under-the-arm (Axillary) Use

This method can be used for babies and young children.

  • Wipe the underarm with a towel.
  • Place the probe tip under the arm so the tip is touching the skin and position the arm next to the body (Fig. 6). With a young child, it is sometimes helpful to hug the child to keep their arm next to their body. This ensures that the room air does not affect the reading.
  • When the peak temperature is reached (usually within 11 seconds but sometimes longer for this method), 5 beep signals will sound and the “°C/°F” sign will stop flashing. The temperature measurement is now ready to read and will not change when the thermometer is removed.
    Note: This method produces a temperature reading 0.5°C / 1°F lower than if the temperature were taken orally.
  • Wash the thermometer as recommended.

Rectal Use

Commonly used for babies, young children, or when it is difficult to take an oral or underarm temperature.

  • Lay the patient on his/her side. For a baby, the proper position is to lay on its stomach with legs hanging down, either across your knees or at the edge of a bed or changing table. This positions the infant’s rectum for safe and easy insertion of the thermometer.
  • Gently insert the tip of the thermometer NO MORE THAN 1cm into the rectum. If you detect resistance, stop. Hold the thermometer in place during measurement.
  • When the peak temperature is reached (usually within 10 seconds) 5 beep signals will sound and the “°C/°F” sign will stop flashing. The temperature measurement is now ready to read and will not change when the thermometer is removed.
    NOTE: This method produces a temperature reading 0.5°C / 1°F higher than if the temperature were taken orally.
  • Wash the thermometer as recommended.

The Vicks® Fever InSight® Thermometer comes with the patented “Fever InSight®” feature which offers a color indicator with the temperature reading. This feature will help you explain to your child the meaning of temperature. It also helps by distracting your child from possible fear associated with temperature taking, especially with young children.

  • For readings between 36.1-37.1°C / 97-98.8°F, the screen will display green as the backlight color indicating the temperature is within the “normal” range.
  • For readings between 37.2-38.2°C / 99-100.7°F, the screen will display yellow as the backlight color indicating a slight elevation in temperature.
  • For readings 38.3°C / 101°F and above, the screen will display red as the backlight color indicating possible fever. The Fever InSight® feature continues for about 5 seconds.


Turn the thermometer off by pressing the On/Off button. If you forget to turn it off, the thermometer will automatically turn off after approximately 1 1/2 minutes.


When the power is off, press and hold the On/Off button for 4 seconds, when the “M” symbol disappears, release the button and press the button to switch from °C to °F or °F to °C . After 3 seconds idle, the thermometer enters into the ready-for-measurement mode.


  • Clean the thermometer by washing it with soap and warm water or rubbing alcohol (70% isopropyl alcohol).
  • Wipe dry with soft cloth.
  • DO NOT BOIL OR WASH IN THE DISHWASHER. This will cause the thermometer to no longer function and will void the warranty.
  • Do not wash with any thinner or chemical solvent.
