3.1 Overview
Infrared thermometer measures the body temperature based on detecting the infrared
energy emitted from the eardrum or the forehead. Users can quickly get measurement
results after positioning properly the temperature probe in the ear canal or on the
forehead.
Normal body temperature hasa range. The following table shows that this normal
range also varies by measuring different site. Therefore, readings from different site
should not be directly compared. Tell your doctor what type of thermometer you used
and what part of body you measured are very important. Also keep this in mind if you
are diagnosing yourself.
Measuring site Normal range of temperature
Forehead 36.1℃to 37.5℃(97.0℉ to 99.5℉)
Ear 35.8℃to 38.0℃(96.4℉ to 100.4℉)

5. Direction for use
Please load the batteries before using the thermometer at the first time and take out
the batteries when you don’t use the thermometer for a long time, such as over one
month.
Additionally, refer to the part 3 of Fig. 3, this thermometer is one button design, so

8
actually it is the same thing when we describe ‘the Power button’, ‘the Measure button’
and ‘the Set button’in subsequent instructions.
5.1 Take your forehead temperature
Press the Power button to power on.
Keep the probe cover touch the middle of your forehead, then press and release the
button. About 1 second later, beep will be heard, at that time you can get the readings.

Note: The forehead measurement is an indicative reading. The measured forehead
temperature can fluctuate up to 0.5℃/1℉from your actual body temperature. Please be
aware of the factors that influence the accuracy as described in the sections of
‘Temperature taking tips’and ‘Warnings and Precautions’.
In order to improve the accuracy, please make sure your forehead is not covered
by hair, sweat or dirt.
Make sure the probe sensor is clean before using the thermometer.
Before using the thermometer, ensure that both the user and the thermometer
remain in the same room with stable airflow and room temperature is between10.0℃

Fig. 8
Please make sure that your ear is clean, without earwax or obstructions.
The temperature is slightly difference between left ear and right ear. So please do
not to compare the readings of left ear and right ear directly and keep the same ear to
measure the temperature each time.
Do not force the thermometer probe into the ear canal. Otherwise, the ear canal may
get hurt.
Be careful when taking ear temperature on a child, whose ear canal is small.
When taking the ear temperature for a child aged over 1 year or an adult, gently pull
the ear up and back to make the ear canal become straight, so that the probe can receive
an infrared ray from the eardrum.

13
symbols, close the battery cover, the thermometer can be restored to normal use.
Take out the batteries if the thermometer will not be used for more than one month.
6. Common sense of temperature measurement
1) It is important to know each individual normal temperature when they are well.
This is the only way to accurately diagnose a fever. Record readings twice in a day,
early morning and late afternoon. Take the average of the two temperatures to
calculate normal oral equivalent temperature. Always take the temperature in the
same location, since the temperature readings may vary from different locations on
the forehead.
2) The normal temperature of a child can be as high as 37.7℃/99.9℉or as low as
36.1℃/97.0℉, please note that this thermometer reads 0.5℃/0.9℉lower than a
rectal digital thermometer.
3) External factors may influence ear temperatures, including when an individual has:
a) been lying on one ear or the other
b) earwax
c) been exposed to very hot or very cold environment
d) been just swimming or bathing
In these cases, return to normal condition by wait quietly 30 minutes prior to taking a
temperature.
Use the untreated ear if prescription ear drops or other ear medications have been
placed in the ear canal.
4) Users will be measured and the thermometer should stay in a steady-state room
condition for at least 30 minutes.

14
5) Before place the thermometer probe on your forehead, remove the hair, dirt, or
sweat of the test area. Wait 10 minutes after cleaning before measuring temperature.
6) Use an alcohol swab to carefully clean the sensor and wait for 5 minutes before
taking a measurement on other people. Wipe your forehead with a warm or cool
cloth may affect the reading. It is advised to wait 10 minutes before taking a
reading.
7) In the following situations it is recommended that measure 3-5 times with the same
location and take the highest one as the reading:
a) Newborn infants in the first 100 days;
b) Children under 3 years of age with compromised immune
c) When the user is learning how to use the thermometer for the first time until
he/she has familiarized himself/herself with the instrument and obtains consistent
readings.
7. Cleaning and disinfection
7.1 Cleaning
Wipe the thermometer body with a slightly damp soft cloth, and gently dry the body
with a piece of tissue paper, take care not to scratch the surface of LED display screen.
Can only use cotton swabs dip in anhydrous ethanol to clean the infrared sensor
lens.

15
Fig. 9
Keep water off the infrared sensor lens during the cleaning process. Otherwise,
the lens may be damaged.
The infrared sensor lens may be scratched if it is cleaned with a piece of tissue
paper, resulting in inaccurate readings.
Do not touch the infrared sensor lens with hard objects.
Never use abrasive cleaning agents, thinners or benzene for cleaning.
Never immerse anypart of the thermometer into liquid,or allow liquid to enter
thethermometer.
7.2 Disinfection
Disinfect the thermometer body and the area around the probe with a soft cloth
slightly moistened with 75% medical alcohol, not to disinfect the infrared sensor lens.
Because 75% medical alcohol contains water, which may damage infrared sensors.
Do not use hot steam or ultraviolet radiation for disinfection.Otherwise,the
thermometer may be damaged or quickly aged.
