need to receive medical attention. People who are on antibiotics, analgesics, or
antipyretics should not be assessed solely on temperature readings to determine
the severity of their illness.
9) Temperature elevation may signal a serious illness, especially in
adults who are old, frail, have a weakened immune system, orneonates and infants.
Please seek professional advice immediately when there is a temperature elevation
and if you are taking temperature for whom are:

monitoring purposes.

7. Product Description
1) Overview
The Infrared Thermometer measures the body temperature based on the
infrared energy emitted from the forehead. Users can quickly get measurement
results after properly scanning the forehead.
Normal body temperature is a range. The following tables show that this normal
range also varies by site. Therefore, readings from different sites should not be
directly compared. Tell your doctor what type of thermometer you used to take
your temperature and on what part of the body. Also, please bear this in mind if
you are diagnosing yourself.
2) Structure
The thermometer consists of a shell, an LCD, a measure button, a beeper, an
infrared temperature sensor, and a microprocessor.
14) Do not take a measurement while or immediately after nursing a baby.
15) Patients should not drink, eat, or be physically active before/while
taking the measurement.

3) Operating principle
The infrared temperature sensor collects infrared energy emitted by the skin
surface. After being focused by a lens, the energy is converted into a temperature
reading by the thermopiles and measurement circuits.
4) Indications for use
The non-contact Infrared Thermometer is intended for the measurement of human
body temperatures. The forehead mode is indicated for people of all ages.
8. Features
• Non-contact design, safe and more hygienic to use.
• Quick measurement, less than 1 second
• Accurate and reliable
• Easy operation, one button design
• Multi-functional, can measure forehead, room, liquid and object temperature.
• 35 sets of memories, easy to recall
• Switching between mute and un-mute mode
• Fever alarm function, displayed in orange and red light.
• Switching between °C and °F
• Auto shut-down and power-saving

contact with the skin), press and hold the ‘ ’ button.
Within 1 second, the thermometer will beep and the reading will be displayed on the
LCD screen
NOTE: The forehead measurement is an indicative reading. The measured forehead
temperature can fluctuate up to 1°F/0.5 °C from your actual body temperature.
Please be aware of the factors that influence the accuracy as described in the
sections "Temperature taking tips" and "Warnings and Precautions".
If the eyebrow area is covered with hair, sweat or dirt, please clean the area
beforehand to improve the reading accuracy.
Always check if the lens is clean.
Always make sure the user and the thermometer will have been in the same
room for at least 10 minutes prior to the measurement.

11
2) How to Measure Room/ Object/ Liquid Temperature:
The power must be off to change the mode. Whilst the power is off, press and hold
the ‘Mem’ button for 3 seconds until the icon shows ‘Home’.
Now press the ‘’ button to take a reading.
Keep the thermometer about 1-3cm away from the object/liquid.
The thermometer will beep after 1 second and the reading will
be displayed on the LCD screen.
3) After a measurement
Once the reading has been completed, remove the thermometer away from the
forehead and observe the temperature.
After each measurement, you can enter the recall mode and query earlier
temperature readings.
Do not hold the thermometer for a long time, because it is sensitive to the
ambient temperature.
After each measurement, clean the temperature probe with a soft cloth, and put
the thermometer in a dry and well-ventilated place.
You should wait at least 10 seconds between each measurement.
It is dangerous to make a self-diagnosis or self-treatment based on the obtained
measurement results. For such purposes, please consult a doctor

12
4) Reading your temperature
The following temperature readings can be found In forehead mode. The
thermometer will flash different colours based on the reading
1. If the temperature reading is between 32°C - 37.3°C (89.6°F - 99.2°F),
the green light will last for 12 seconds, with one long beep.
2. If t he temperature reading is between 37.4°C - 37.9°C (99.3°F - 100.3°F),
the orange light will last for 12 seconds, with 3 short beeps, and the value on
the LCD flickers, which is a warning that you may have a light fever.
3. If the temperature reading is between 38°C - 42.9°C (100.4°F - 109.2°F),
the red light will last for 12 seconds, with 5 short beeps, and the value on the LCD
flickers, which is a warning that you may have a high fever.
5) Switching between mute and un-mute
Whilst the power is on, press the “Mute/Unmute” button
to switch the sound on or off, the icon in the LCD display

memory mode, press ‘Mem’ button again to to check the 35 sets of memories one
by one. If there is no value, it will display “---M”.
7) °C/°F conversion
When the thermometer is turned on, long press the “Mute/Unmute’ Button for 5
seconds to change from ºC to ºF or ºF to ºC
8) Temperature compensation adjustment
When the thermometer is powered on, press both the ”Mute/Unmute” button and the
“Mem” button for 2-3 seconds to go to the temperature compensation mode.
Press the ”Mem” button to adjust the temperature from ±0.0 to ±2.0.
Note: All future readings will be automatically adjusted to the value set, for example:
if the adjustment is set to +1.0 a 35C reading will show 36C

13
9) Power off
The unit will shut down automatically after 15 seconds of no use. Or you can keep
pressing the Measure button for 6 seconds until the thermometer turns off.
Caution
1. All the memory records will be lost when the battery is removed or reinstalled
2. All the settings will reset back to default when the battery is removed. If needed
please power on and adjust the new settings.
10) Replace the battery
Slide the battery cover off along the marked direction. Put 2 x AAA batteries
correctly into the compartment.
Remove the batteries if the thermometer will not be used for more than
two months.
12. Temperature taking tips
1) It is important to know each individual's normal temperature when they are well.
This is the only way to accurately diagnose a fever. Record readings twice 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) A child's normal temperature can be as high as 37.7°C (99.9F) or as low as
36.11°C (97.0F). Please note that this unit reads 0.5°C (0.9°F) lower than a rectal
digital thermometer.
3) Holding the thermometer for too long in the hand before taking a measurement
can cause the device to warm up. This means the measurement could be incorrect.
4) Patients and the thermometer should stay in steady-state room condition for at
least 10 minutes.

14
5) Before placing the thermometer sensor onto the forehead, remove dirt, hair,
or sweat from the forehead area. Wait 10 minutes after cleaning before taking
a measurement.
6) Use an alcohol swab to carefully clean the sensor and wait for 5 minutes before
taking a measurement on another patient. Wiping the forehead with a warm or cool
cloth may impact your reading. It is advised to wait 10 minutes before taking a reading.
7) In the following situations it is recommended that 3-5 temperatures in the same
location be taken and the highest one taken as the reading:
• Newborn 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 instrument and obtains consistent readings.
13. Care and cleaning
Use an alcohol swab or cotton swab moistened with 70% alcohol to clean the
thermometer casing and the measuring probe. After the alcohol has completely dried
out, you can take a new measurements.
Ensure that no liquid enters the interior of the thermometer. Never use abrasive
cleaning agents, thinners or benzene for cleaning and never immerse the instrument
in water or other cleaning liquids. Take care not to scratch the surface of the LCD
screen.
