1. Taking a Temperature Reading

- Oral: Place the tip under the tongue, close to the heat pocket. Keep mouth closed.
- Armpit (Axillary): Place the tip in the armpit, ensuring good skin contact. Hold arm firmly against the body.
- Rectal: For infants and young children, lubricate the tip with a water-soluble jelly. Gently insert the tip no more than 1/2 inch into the rectum.
Press the power button to turn on the thermometer. The reading will typically complete in under 8 seconds. The large, lighted display makes it easy to read the temperature, day or night. Fever indication icons provide a quick visual cue about the temperature level.
