To change your thermometer from Celsius to Fahrenheit or vice versa, please follow the below steps:

  1. While the device is powered OFF, press and hold the sound MODE button for 4 seconds.
  2. The screen will change to show °C or °F. Press the sound mode button one more time to change from Fahrenheit to Celsius.
  3. The display will remain on the selected scale for 3 seconds before automatically shutting off. The selected scale will be saved and displayed the next time the device is powered on.

Your thermometer will display a flashing battery symbol on the LCD screen, signaling it is time to change the batteries.

  1. First slide open the battery cover on the back of the thermometer and remove the dead batteries.
  2. Insert 2 new AAA batteries, being sure to align properly as indicated inside the battery door compartment.
  3. Slide the cover back on.

Your thermometer allows you to view the last 10 temperature readings by pressing the "MEMO" button. The most recent temperature will display on the LCD screen. To view the next most recent temperature taken, press the "MEMO" button again.

To clear the memory of previous temperatures, press and hold the "MEMO" button for 4 seconds.

The directions below include detailed instructions on how to view the last 10 temperature readings:

  1. While the device is powered on, hold down the sound mode button
  2. While holding the sound mode button, press the food/bath mode button to cycle through previous readings.
  3. The previous 10 temperatures can be displayed on the LCD screen. The most recent temperature taken will be the first temperature displayed
  4. When the sound mode button and the food/bath mode buttons are both released, the thermometer will be ready to take a temperature again

We recommend cleaning the thermometer between uses. Using an alcohol swab or a cotton swab moistened with alcohol (70% Isopropyl), please follow the below steps:

  1. Carefully wipe the thermometer casing and measuring probe for 90 seconds.
  2. After wiping, allow thermometer to air dry.
  3. Be sure to wait 10 minutes before taking a new measurement.

Please note: Never use abrasive cleaning agents, thinners, or benzene for cleaning, and never immerse the thermometer in water or other cleaning liquids.

  • Let the thermometer and the individual being measured acclimate to the temperature of the room in which the measurement will be taken for 30 minutes.
  • Be sure to wipe away any sweat with a dry cloth. Sweat can cool skin resulting in a false reading. Ensure that the forehead is clean and free from any hair. If you clean the forehead or move hair away from the forehead, wait 10 minutes before taking a measurement.
  • Hold parallel to the forehead.
  • Make sure the individual you are measuring keeps their head still.
  • Hold the thermometer steady. DO NOT swipe!
  • DO NOT move the thermometer until you hear the final beep.
  1. With the device powered On, press the MODE button to switch from human to surface temperature. The screen will change from "body" to "surface temp" on the top of the LCD screen.
  2. When the device is ready, 3 dashed lines will appear on the screen.
  3. Position thermometer 0.4-2 inches (1-5 cm) away from food or bath water. Ensure that you are aiming directly at the food or bath water and not at the food container or walls of the bathtub. Ensure that the thermometer is not directly in-line of steam, as this can impact reading. DO NOT touch food or bath water with the thermometer.
  4. Press the temperature button to take a temperature measurement.
  5. A confirmation beep will be heard, indicating the measurement is complete. The temperature measurement will be displayed on the LCD screen.
  1. To activate the silent mode, press the 'sound mode' button.
  2. The speaker icon will change to a muted speaker icon on the LCD screen. The muted speaker icon indicates the thermometer is in silent mode.
  3. To turn off silent mode press the 'sound mode' button. The muted speaker icon will change to the regular speaker icon.
