months.)
• For children under 1 year: Pull the ear straight back (Fig. 5)
5. While pulling the outer ear, insert the probe snugly into the ear canal
and press the "START" button. Release it, when you hear a beep sound. A
beep indicates measurement is complete. (Fig. 6)
6. Remove the thermometer from the ear. The display shows the
measured temperature.
7. Replace the probe cover after each measurement. To do this, fol-
low the instructions in section 6, (How to apply a new probe cover).
8. In order to assure accurate readings, please wait at least 30 sec-
onds after 3-5 continuous measurements.
NOTE:
• For an infant, it is best to have the child laying
flat with head sideways so the ear is facing towards
you. For an older child or adult, it is best to stand
behind and slightly to the side of the patient.
• Always take measurements in the same ear since temperature
readings may be different from the right and left ear.
• Wait a few minutes before taking ear temperature after sleeping.
• It is recommended that three temperatures in the same ear be taken
and the highest one taken as the reading. This is very important with:
1) Newborn infants in the first 100 days.
2) Children under three years of age with a compromised immune system and for whom
the presence or absence of fever is critical.
3) When the user is learning how to use the IR thermometer for the first time until he/she has
familiarized himself/herself with the instrument and obtains consistent readings.
Caution: If you are not confident with readings obtained, confirm temperature
with a standard digital thermometer.

8. Changing from Fahrenheit to Celsius and vice-versa

The ADC® Digital 424 Thermometer can display temperature measure-
ments in either Fahrenheit or Celsius. To switch the display between °F

the display will show ---°C or ---°F. Release the Start button. Push the
Start button again to toggle between °C or °F. Five seconds after complet-
ing the change to °C or °F, the unit will prepare for a measurement, and
beep when ready.
