Important Safety Instructions

•  Never use the thermometer for purposes other than body or surface temperature measurement. Please follow the safety precautions when using on children.

• Always use the thermometer with a new undamaged Probe Cover for each measurement to prevent infection. Readings taken without probe covers will not be accurate. Only ADC® brand probe covers can ensure that you get an accurate measurement from the 424 Digital Ear Thermometer.
  Never immerse the thermometer into water or other liquids. (not waterproof) For cleaning and disinfecting please follow the instructions in section 10, “Cleaning and Storage”.

• Keep the instrument and the probe covers away from direct exposure to the sun and keep it in a dust-free, dry area at a temperature between 10° – 40° (50°F – 104°F).

• If the instrument is not going to be used for a prolonged period the battery should be removed.

• Ensure that children do not use the instrument unsupervised; some parts are small enough to be swallowed.

• Do not use the thermometer if there are signs of damage on the probe or on the instrument itself. If damaged, do not attempt to repair the instrument!

• Earwax in the ear canal may cause a lower temperature reading. Make sure subject’s ear canal is clean to ensure an accurate reading. Use caution when cleaning ears.

• The ADC® 424 Digital Ear Thermometer consists of high quality precision parts. Protect it from severe impact and shock. Keep the unit in its storage case when not in use.

WARNING:

• Please keep the probe covers out of the reach of children. They may present a choking hazard.

How to Measure Body Temperature

The ADC® 424 Digital Ear Thermometer measures the heat radiated from the eardrum and the sur-rounding tissue. This energy is collected through the lens and converted to a temperature value. The measured reading obtained directly from the eardrum (Tympanic Membrane) can ensure the most accurate body temperature. Measurements taken from the surrounding tissue of the ear canal generate lower readings and may result in misdiagnosis of a fever.

To avoid an inaccurate measurement:

• Use ONLY ADC® probe covers, as this unit is calibrated to work with probe covers. Straighten the ear canal by gently pulling the middle of the ear back and up. This ensures measurement of heat from the eardrum. (Please note: Pull outer ear out for newborns – age 1)
• Place the probe firmly into the ear canal. Press the Start button and keep the probe in the ear until the thermometer beeps to indicate completion of the measurement.

The 424 Digital Ear Thermometer has been clinically tested and proven to be safe and accurate when used in accordance with operating instructions.

How to Read the Display

How to Apply a New Probe Cover

1. Place a probe cover onto the storage case hole with paper side upwards. Align the cover to fit the hole exactly.

2. Take the unit, vertically penetrate the probe into the center part of the probe cover.

3. Completely push the probe into the probe cover holder hole.
   Push firmly.

4. After feeling a slight click, take out the probe. The cover should be securely attached.

Please Note: Unit is calibrated to work with probe covers. Only use of ADC® probe covers ensures accuracy and hygienic use.

NOTE

• In order to avoid spreading germs, please use a new probe cover for each measurement.
• Check to ensure probe cover is fitted on firmly before use (please see the diagrams below). If the probe cover is broken, discard and apply a new one immediately.

Directions for Use

Important: Prior to every measurement, fit a new undamaged Probe Cover on the measuring probe. Failure to do so may result in incorrect temperature readings.

1. Press the ON/OFF button. The display is activated to show all symbols for 2 seconds. (Fig. 1)

2. The last measurement reading will be shown on the display automatically for 3 seconds with the “M“ symbol visible. (Fig. 2)

3. A beep sound is heard. The °C or °F symbol will flash. The thermometer is ready to measure. (Fig. 3)

4. Straighten the ear canal by pulling the outer ear up and back to give a clear view of the eardrum.

   • Children ages 1 year to adult:

   • Pull the ear up and back. (Fig. 4)
     (Caution: Many pediatricians suggest use of ear thermometers for children older than 6 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, follow the instructions in section 6, (How to apply a new probe cover).

8. In order to assure accurate readings, please wait at least 30 seconds 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.

Changing from Fahrenheit to Celsius and vice-versa

The ADC® Digital 424 Thermometer can display temperature measurements in either Fahrenheit or Celsius. To switch the display between °F and °C, turn the unit off. Press and hold the Start button for 5 seconds, 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 completing the change to °C or °F, the unit will prepare for a measurement, and beep when ready.

Error Messages

Caution: High fever requires immediate medical attention!

Cleaning and Storage

Use an alcohol swab or cotton swab moistened with alcohol (70% Isopropyl) to clean the thermometer casing and the measuring probe. Ensure that no liquid enters the interior of the thermometer.
Never use abrasive cleaning agents, thinners or gasoline for cleaning and never immerse the instrument in water or other cleaning liquids.

Take care not to scratch the surface of the lens or display.

Remove the battery from the instrument if it is not required for extended periods of time in order to avoid damage to the thermometer resulting from a leaking battery.
Please Note: Ear wax or dirt on the lens will result in an
inaccurate reading. Clean the lens as indicated above.
