HOW TO TAKE A TEMPERATURE

1. Select oral, underarm or rectal as your measurement site based on each individual.

    Clean thermometer with soap and water prior to use.

2. Push the operating button located on the top of the thermometer. The thermometer 

will beep and the display will read: as illustrated in Figure 1. This is a function 

check indicating that the unit is working properly. Immediately after, “Last memory” 

and the temperature will be displayed, then “LO°C" with the °C/°F flashing will 

indicate that the thermometer is ready to use, as illustrated in Figure 2.

3. While taking a temperature, the °C/°F symbol flashes as long as the temperature 

increases.

4. The thermometer will beep twice, indicating that the peak temperature has 

been reached, right after the beep is heard the screen will light up green if the 

temperature is below 37.6°C/99.7°F. If the temperature is 37.6°C/99.7°F and above, 

rapid beeps will sound and the screen will light up red indicating a fever.

 NOTE:

 The LCD will display “LO°C” if the measurement taken is below 32.0°C/89.6°F. It will 

display “HI°C” if the measurement is above 43.9°C/111.0°F.

5. To prolong the life of the battery, turn the thermometer off after each use by pressing the 

operating button briefly, otherwise the unit will turn off automatically in approximately 3 

minutes.

 NOTE:

 For best results, wait 3 minutes between temperature measurements.

6. To switch the thermometer from °C to °F. Press and hold the operating button when the 

thermometer is turned off, once “LO°C” is displayed with the °C not flashing, press the 

operating button again to toggle between °C and °F. 

ORAL USE:

• Do not drink hot or cold fluids, exercise, smoke or perform other activities prior to a 

measurement that will raise or lower temperature readings when compared to your normal 

average temperature. The mouth should remain closed for up to 5 minutes before attempting a 

reading.

• Place the probe tip well under the tongue and wait until a beep is heard. Instruct children not to 

bite down on the probe.

UNDERARM (AXILLARY) USE:

• Wipe arm with a dry towel.

• Place the probe tip in the hollow of the armpit and bring arm down against the body and wait 

until a beep is heard.

RECTAL USE:

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

temperature.

• Lubricate the thermometer with a water-soluble personal lubricant or petroleum jelly.

• Gently insert the probe tip no more than 0.5 inch or 1.3cm into the rectum, and wait until a beep 

is heard.

 

Do not force the tip into the rectum if resistance is encountered.
