Normal Temperature and Fever Ranges

MethodNormal TemperatureFever Range
Rectal97.3°F – 100.4°F100.4°F +
Oral97.0°F – 99.6°F99.6°F +
Underarm95.4°F – 98.6°F98.6°F +

For Rectal Use

The American Academy of Pediatrics (AAP) recommends rectal temperature checks for babies up to one year, and it is considered the best method until age three. Ensure the thermometer is in Rectal ("rct") mode.

  1. Lubricate the silver tip with coconut oil or another natural lubricant.
  2. Press the small bump on the thermometer probe to turn on the LED light for visibility.
  3. Gently insert the thermometer tip up to the insertion stopper while lifting the baby's legs.
  4. Do not insert past the point of resistance.

For Oral or Underarm Use

Confirm the thermometer is in the correct mode: Oral ("orl") or Underarm ("udr").

  1. Press the white probe button on the side and flip the tip into oral/underarm mode.
  2. Oral Use (recommended for ages four and up): Place the thermometer tip under the tongue.
  3. Underarm Use: Place the thermometer probe with the tip in the armpit and keep the arm firmly pressed against the side.

For accurate underarm readings, always wait for the 30-second final reading, as the 10-second reading may be affected by environmental factors.

Taking a Temperature (10 or 30-Second Reading)

  1. Press the Power Button to turn the thermometer on. The last temperature reading will appear on the LCD screen.
  2. The selected reading mode ("rct," "orl," "udr") will be displayed.
  3. The screen will show "---" and the temperature unit (°F or °C).
  4. Insert the thermometer into the appropriate body part based on the mode setting. A loading "wheel" will appear on the screen while registering the temperature.
  5. 10-Second Read: The thermometer will beep and flash a temperature reading after 10 seconds.
  6. 30-Second Read: Keep the thermometer inserted. The screen will continue to flash for another 20 seconds. The thermometer will beep and display the final temperature reading once 30 seconds have passed.
  7. Wait at least one minute before attempting a new measurement.
  8. Press the Power Button to turn off the thermometer. This can be done at any time.
  9. Sanitize the thermometer before and after all readings, especially if switching between rectal and oral use.

Changing Units (°F to °C)

Turn the thermometer on. When the last temperature reading flashes, hold the button for 3 seconds. Press the button once to scroll to the next unit. Wait 3 seconds or press the button for 3 seconds to confirm your selection.

  2. Hold the button for 3 seconds when the mode ("rct," "orl," "udr") flashes.
  3. Press the button once to scroll to the next mode.
  4. Wait 3 seconds for the thermometer to register the selected mode, or press the button for 3 seconds to confirm and proceed.

(Dead Battery)Battery icon is flashing, cannot be measurable.Check battery and replace with a new battery if necessary.

Normal Body Temperature / Fever Indicator

Body temperature can vary between 97°F and 100.0°F and still be considered normal. The medically accepted 'normal' body temperature is 98.6°F. Body temperature is commonly lower upon waking than at any other time during the day.

Temperature readings vary based on the body location. Oral readings between 97°F (36.1°C) and 100°F (37.7°C) are considered normal. A rectal temperature reading is typically 1°F (0.5°C) higher, while an underarm (axillary) temperature reading is typically 1°F (0.5°C) lower.

A fever is defined as a body temperature elevated above an individual's normal. It's important to establish an individual's normal temperature by tracking it consistently at the same body site and time when they are healthy, to accurately determine if a fever is present.
