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.
Your VICKS ® ComfortFlex™ Digital 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, avoid eating or drinking any liquids, exercising, taking showers or baths, or smoking.
IMPORTANT: Before first use, remove label from the display.
Disposable probe covers are provided with your VICKS ® ComfortFlex™ Digital Thermometer. Place a cover on the probe tip each time the thermometer is used to help prevent spread of germs. Additional probe covers can be purchased at most drug stores or pharmacy departments.
1. Turn unit on by pressing the On/Off button (Fig. 1).
2. Wait for unit to get ready
– A beep will sound and the display will show a test (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
Under-the-arm (Axillary) Use
This method is used for babies and young children.
1. Wipe the underarm with a towel.
2. Place the probe tip under the arm so the tip is touching the skin and position your arm next to your 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.
3. When the peak temperature is reached (usually 11 seconds but sometimes longer for this method), 2 beep signals will sound and the “°F” sign will stop flashing. The temperature is now ready to read and will not change when the thermometer is removed.
Note: This method produces a temperature 1°lower than a temperature taken orally.
4. 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.
1. Cover the thermometer’s tip with a probe cover and lubricate with a water-soluble jelly for easier insertion. Do not use petroleum jelly. Read the label of the lubricant to be sure you are using the right kind.
2. Lay the patient on his/her side. If the patient is an infant, the proper position for a baby 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.
3. Gently insert the tip of the thermometer NO MORE THAN 1/2 inch into the rectum. If you detect resistance, stop. Hold the thermometer in place during measurement.
4. When the peak temperature is reached (usually 10 seconds) 2 beep signals will sound and the “°F” sign will stop flashing. The temperature is now ready to read and will not change when the thermometer is removed.
NOTE: This method produces a temperature 1°higher than a temperature taken orally.
5. Dispose of used probe cover and wash the thermometer as recommended.
The Vicks ® ComfortFlex™ Digital Thermometer comes with the patented “Fever InSight” feature offers a color indicator with the temperature readout to better understand the temperature measurement.
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 3.5 minutes.
The VICKS ® ComfortFlex™ Digital Thermometer features a long life, mercury free battery. When the

1. Using a coin, unlock the battery cover and carefully remove the battery with a non-metallic instrument.
2. Replace the battery with a 1.55V, L41 alkaline or CR1225 silver oxide type or equivalent. Insert the new battery with the positive (+) side facing the battery cover.
3. Carefully replace the battery cover and, using a coin, tighten the cover.
