TEMPERATURE READINGS

Temperature readings vary from person to person. Although there is no one “normal” temperature reading, a
temperature, taken orally, ranging between 97°F and 100°F is considered normal. A rectal temperature is generally
1° higher and an underarm (axillary) temperature will be 1° 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.

DIGITAL

THERMOMETER

Press the On/Off button to activate the thermometer. A beep will sound and the display
light will come on. The display will first show the LCD display test (Fig. 1) and then
show the last reading. After 5 seconds, the display will be in the ready mode (Fig. 2) and
display light will go off.

ORAL USE

1. Cover the thermometer’s tip with a probe cover.
2. Place the probe tip well under the tongue. (Fig. 3) Place sensor tip in areas marked

with “

”. The mouth should remain closed during the measurement to ensure an

accurate reading. Be careful not to bite the thermometer.

3. When the peak temperature is reached (10-20 seconds), 10 beep signals will sound

and the “°F” sign will stop flashing and display light will come on. The temperature is
now ready to read and will not change when the thermometer is removed.

4. Turn the thermometer off by pressing the On/Off button. The display light will come on automatically to

illuminate the last reading, then unit will power off. If you forget to turn it off, the thermometer will automatically
turn off after approximately 9 minutes.

5. Dispose of used probe cover and wash the thermometer as recommended.

UNDER-THE-ARM (AXILLARY) USE

This method used for babies and young children but less accurate and takes longer.
1. Wipe the underarm with a towel.
2. Cover the thermometer’s tip with a probe cover.
3. Place the probe tip under the arm so the tip is touching the skin and position

your arm next to your body (Fig. 4). 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 probe.

4. When the peak temperature is reached (usually 20-30 seconds but sometimes longer for this method), 

10 beep signals will sound and the “°F” sign will stop flashing and display light will come on. The temperature is
now ready to read and will not change when the thermometer is removed. Remember that this method produces
a temperature 1° lower than a temperature taken orally.

5. Turn the thermometer off by pressing the On/Off button. The display light will come on automatically to

illuminate the last reading, then unit will power off. If you forget to turn it off, the thermometer will automatically
turn off after approximately 9 minutes.

6. Dispose of used probe cover and wash the thermometer as recommended.
