How this Thermometer measures Temperature

This thermometer measures infrared energy radiated from the eardrum and the surrounding tissue. This energy is collected through the lens and converted to a temperature value. The measured reading obtained directly from the eardrum (Tympanic Membrane) ensures the most accurate ear temperature. Measurements taken from the surrounding tissue of the ear canal generate lower readings and may result in misdiagnosis of fever.

To avoid an inaccurate measurement

Switch on the thermometer by pressing the ON/OFF button ④.
After one beep is heard (and the temperature scale icon is flashing), straighten the ear canal by gently pulling the middle of the ear back and up.
Place the probe ① firmly into the ear canal, press the START button ③ and keep the probe in the ear until the thermometer beeps to signal the completion of the measurement.

Control Displays and Symbols

Straighten the ear canal by pulling the ear up and back to give a clear view of the eardrum.
● For children under 1 year; pull the ear straight back.
● For children of 1 year to adult; pull the ear up and back. Also refer to the short instructions at the front.
While gently pulling the ear, insert the probe snugly into the ear canal ( about 1 sec. ) and immediately press the START button ③.
Release the button and wait for the beep sound. This indicates the end of the measurement.
Remove the thermometer from the ear canal. The display shows the measured temperature ⑩.

NOTE:

Patients and thermometer should stay in similar room condition for at least 30 minutes.

To ensure accurate readings, wait at least 30 sec. after 3-5 continuous measurements.
Accumulation of ear wax on the probe can result in less accurate temperature readings or cross infection between users.
It is essential that the probe is cleaned after every measurement. Therefore, this device reminds the user to clean the probe when turning off the device. «CLEAN ME» ㉑ is displayed and the probe LED light will flash for 3 seconds. For cleaning, follow the instructions in the «Cleaning and Disinfecting» section.
After cleaning the measuring sensor ① with alcohol, wait 5 minutes before taking the next measurement, in order to allow the thermometer to reach its operating reference temperature.
10 short beeps and a red LCD backlight alert the patient that he/ she may have a temperature equal to or higher than 37.5 °C.
For an infant, it is best to have the child lying flat with his/her head sideways so the ear is facing upwards. For an older child or adult, it is best to stand behind and slightly to the side of the patient.
Always take the temperature in the same ear, since the temperature readings may be different from ear to ear.
In the following situations it is recommended that three temperatures in the same ear be taken and the highest one taken as the reading:

New born infants in the first 100 days.
Children under three years of age with a compromised immune system and for whom the presence or absence of fever is critical.
When the user is learning how to use the thermometer for the first time until he/she has familiarized himself/herself with the device and obtains consistent readings.
If the measurement is surprisingly low.

Don’t take a measurement while or immediately after nursing a baby.
Don’t use the thermometer in high humidity environments.
Patients should not drink, eat or exercise before/while taking the measurement.
Doctors recommend rectal measurement for newborn infants within the first 6 months, as all other measuring methods might lead to ambiguous results.
Readings from different measuring sites should not be compared as the normal body temperature varies by measuring site and time of day, being highest in the evening
and lowest about one hour before waking up.
Normal body temperature ranges:
– Axillar: 34.7 – 37.3 °C / 94.5 – 99.1 °F
– Oral: 35.5 – 37.5 °C / 95.9 – 99.5 °F
