3. Product description
3.1 Overview
The Medical Infrared Thermometer measures body temperature
based on detecting infrared energy emitted from the eardrum or
forehead. Users can quickly obtain measurement results after
properly positioning the temperature probe in the ear canal or on
the forehead.
Normal body temperature has a range. The following table shows
that this range also varies by measuring temperature at different
sites. Therefore, readings from different sites should not be directly
compared. It is very important to tell your doctor which type of
thermometer you used and which part of the body you measured.
Also keep this in mind if you are diagnosing yourself.

appetite or activity, seizure, muscle pain, shivering, stiff neck, pain
when urinating, etc., even in the absence of fever.
8) Those who exhibit a normal temperature may still need to
receive medical attention. When determining the severity of illness
of people on antibiotics, analgesics or antipyretics, temperature
readings should not be solely relied upon.
- 6 -
9) Temperature elevation may signal a serious illness, especially in
adults who are elderly, frail or have a weakened immune system, or
neonates and infants. Please seek professional advice immediately
when there is a temperature elevation in a person who meets any
of the following criteria:
Over 60 years of age (fever may be dulled or even absent in
elderly patients)
Diagnosed with diabetes mellitus or a weakened immune
system (e.g. HIV positive, cancer, chemotherapy, chronic
steroid treatment, splenectomy)
Bedridden (e.g. nursing home patient, stroke, chronic illness)
A transplant patient (e.g. liver, heart, lung, kidney)
10) This thermometer is not intended for premature babies or small

5. Directions for use
Please load the batteries before using the thermometer. Take the
batteries out if you will not use the thermometer for a long time,
such as over one month.
Additionally, referring to Part 3 in Fig. 3, this thermometer has a
one-button design, so when we describe the ‘Power button’,
‘Measure button’ and ‘Set button’ in this manual, we are referring
to the same button.
5.1 Take your forehead temperature
Press the Power button to power on.
Let the probe cover touch the middle of your forehead, then press
and release the button. About 1 second later, a beep will be heard
and the reading will be obtained. In Forehead Mode, the symbol
will be displayed on the screen.
Fig. 7
Note: forehead measurement is an indicative reading. Measured
forehead temperature can fluctuate up to 0.5℃/1℉ from your
actual body temperature. Please be aware of factors that influence
accuracy as described in the sections ‘Temperature-taking tips’
and ‘Warnings and Precautions’.
- 8 -
In order to improve accuracy, please make sure that your
!
forehead is free from hair, sweat or dirt.
!
Make sure the probe sensor is clean before using the thermome-
ter.
Ensure that both the user and thermometer remain in the same
!
room with a stable airflow and a room temperature between
10.0‒40.0℃ (50.0‒104.0℉) for at least 30 minutes before using the
thermometer.
5.2 Take your ear temperature
Press the Power button to power on.
Take off the probe cover and fit the probe snuggly into the ear
canal, then press and release the button. About 1 second later, a
beep will be heard and the reading will be obtained. In Ear Mode,
the symbol will be displayed on the screen.
Fig. 8
Please make sure that your ear is clean and free from without
!
earwax or obstructions.
!
There is a slight difference in temperature between the left and
right ear. As such, please do not to compare the readings of the left
ear and right ear directly, but use the same ear each time.
Do not force the thermometer probe into the ear canal, or else
!
the ear canal may be injured.
- 9 -
Be careful when taking the ear temperature of a child, as their
!
ear canals are small.
!
When taking the ear temperature of a child aged over 1 year or
an adult, gently pull the ear up and back to make the ear canal
straight, allowing the probe to receive infrared rays from the
eardrum.
5.3 Recall saved readings
The thermometer can store 32 sets of measurement data. When the
data is full, the last reading will always replace the first.
If you wish to review previous measurement data, when the
thermometer is shut down, press the Sets button for about 3
seconds until you see the ‘M’ symbol flicker on the screen, then
release the button.
When you press the button, you will see the number ‘1’ appear on
the right side of the screen; this means the first saved reading. The
number ‘1’ will then disappear quickly and the first saved
temperature reading will appear. By pressing the button, you can go
through all the saved temperature readings one by one. After
reviewing the saved readings, press the button for about 5 seconds
to automatically save the readings and shut down the thermometer.
5.4 ℃ and ℉ conversion
If you wish to convert ℃ to ℉ or ℉ to ℃, when the thermometer is
shut down, press the Set button for about 6 seconds until you see
the ‘℃’ symbol or the ‘℉’ symbol flicker on the screen, then
release the button. Press the button again and the ℃ symbol or ℉
symbol will be converted to the other.
Do not release the button when the “M” symbol appears, but only
release it when the ‘℃’ symbol or ‘℉’ symbol appears. After
finishing conversion, press the button for about 5 seconds to
automatically save the setting and shut down the thermometer.
- 10 -
5.5 Turn on or off the buzzer/speaker/vibration
The PC809, PC809EV, PC809V models are different in how they
interact with users when measurement is complete: the PC809 uses
a buzzer to ‘beep’, the PC809EV communicates the temperature in
English through a speaker and the PC809V uses a motor to vibrate.
Please check the label on the back to determine which thermome-
ter model you are using.
If you want to turn on/off the buzzer/speaker/vibration, when the
thermometer is shut down, press the Set button for about 9
seconds until you see the ‘ON’ symbol or ‘OFF’ symbol appear
on the screen, then release the button. Press the Set button again
and the ‘ON’ symbol or ‘OFF’ symbol will be converted to the
other.

cally save the setting and shut down the thermometer.
5.6 Set threshold for low fever
This thermometer has 37.5℃/99.5℉ preset as an alarm temperature
for low fever. However, 37.5℃/99.5℉ is only a reference value. At
this temperature, different people feel different, with some feeling
uncomfortable and others feeling fine. If you do not agree with this
low fever threshold, after consulting your doctor, you can manually
change it to suit your own situation.
When the thermometer is shut down, press the Set button for about
12 seconds until you see the orange status light on the screen,
then release the button. Ignore the other symbols that appear in
the process.
By pressing the Set button, you can increase the threshold by 0.1
℃/0.2℉ each time. The adjustment range is from 37.5℃/99.5℉ to
37.9℃/100.2℉. Once it reaches the Max. value, press the button
again; it will return to the Min. value and the cycle will repeat.
After adjustment is complete, press the button for about 5 seconds
to automatically save the setting and shut down the thermometer.
- 11 -
5.7 Set threshold for high fever
This thermometer has 38.0℃/100.4℉ preset as an alarm tempera-
ture for high fever. However, 38.0℃/100.4℉ is only a classic
reference value. At this temperature, different people feel different,
with some feeling bad and others not feeling too bad. If you do not
agree with this high fever threshold, after consulting your doctor,
you can manually change it to suit your own situation.
When the thermometer is shut down, press the Set button for about
15 seconds until you see the red status light on the screen, then
release the button. Ignore the other symbols that appear in the
process.
By pressing the Set button, you can increase the threshold by 0.1
℃/0.2℉ each time. The adjustment range is from 38.0℃/100.4℉ to
38.9℃/102.0℉. Once it reaches the Max. value, press the button
again; it will return to the Min. value and the cycle will repeat.
After adjustment is complete, press the button for about 5 seconds
to automatically save the setting and shut down the thermometer.

6. Temperature-taking tips
1) It is important to know the normal temperature of each
individual when they are well. This is the only way to accurately
diagnose a fever. Record readings twice a day, once in the early
morning and once in the late afternoon. Take the average of these
two temperatures to obtain the normal oral equivalent tempera-
ture. As temperature readings may vary among different locations
on the forehead, always take the temperature in the same location.
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 temperature, including when
an individual has:
a) been lying on one ear or the other;
b) earwax;
c) been exposed to a very hot or very cold environment;
d) just been swimming or bathing.
In these cases, return to normal condition by waiting quietly for 30
minutes before taking the reading.
If prescription ear drops or other ear medications have been placed
in the ear canal, use the untreated ear.
4) The person to be measured and the thermometer should stay in
a steady-state room condition for at least 30 minutes before taking
the reading.
5) Before placing the thermometer probe on the forehead, remove
hair, dirt or sweat from the measurement area. Wait 10 minutes
after cleaning before taking the reading.
6) Before taking the temperature of another person, clean the
sensor carefully with an alcohol swab and wait for 5 minutes.
Wiping the forehead with a warm or cool cloth may affect the
reading; in this case, it is advisable to wait 10 minutes before taking
the reading.
- 13 -
7) In the following situations, it is recommended to measure 3‒5
times in the same location and take the highest temperature as the
reading:
a) Newborn infants in the first 100 days;
b) Children under 3 years of age with compromised immune
systems;
c) When the user is learning how to use the thermometer for the
first time, until he/she has familiarized him/herself with the
instrument and can obtain consistent readings.
7.Cleaning and disinfection
7.1 Cleaning
Wipe the thermometer shell 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 the LED display screen.
Only use cotton swabs dipped in anhydrous ethanol to clean the
infrared sensor lens.
Fig. 9
- 14 -
Keep the infrared sensor lens away from water during the
!
cleaning process, or else it 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 allow the infrared sensor lens to make contact with hard
!
objects.
Never use abrasive cleaning agents, thinners or benzene for
!
cleaning.
Never immerse any part of the thermometer in liquid, or allow
!
liquid to enter the device.
7.2 Disinfection
Disinfect the thermometer body and the area around the probe
with a soft cloth slightly moistened with 75% medical alcohol. Do
not use the same method to disinfect the infrared sensor, as 75%
medical alcohol contains water which may damage the lens.
Do not use hot steam or ultraviolet radiation for disinfection, or
!
else the thermometer may be damaged or quickly aged.

The Infrared Thermometer is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The
customer or user of the infrared thermometer can help prevent
electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment
(transmitters) and the thermometer as recommended below, according
to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in metres (m) can be estimated
using the equation applicable to the frequency of the transmitter, where
P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
