5. Precautions before use:
1) Make sure follow the below steps before using:
Step 1: Use a traditional thermometer to measure, assuming got the value is 7.5 ° C (99.5 ° F)
Step 2: Then, use our infrared forehead thermometer to measure the same person, the distance is 3-5
cm between the thermometer and the forehead (be careful to remove any obstacles that may affect the
measurement, such as hair, sweat, etc.), if you get the same temperature 37.5 ° C (99.5 ° F), the
infrared forehead thermometer is set up and ready for use. If you get a low reading, such as 36.4 ° C
(97.5 ° F, a difference of 1.1 ° C (2.0 ° F), you need to correct the infrared forehead thermometer, plus
the difference. Calibration steps "Note! Non-professional not operational!" After 5S, press and hold
the + key and the function key to power on. After hearing 2 beeps, press the-key to enter the

or other reasons, please aim at the earlobe.still no covering by hair,
sweat, cosmetics or hats
Picture 6:
3) The boot time is extended by 1 to 2 seconds if the thermometer has not been used for a long time
that due to the thermometer will inspect the environment temp.
4) A person's body temperature changes at different times of the day, and is also affected by other
external conditions, such as age, gender, and skin color.
5) It is recommended to measure about three times at a time, whichever is the most displayed data.
11. Reference temperature
11.1 Normal body temperature range at different measurement parts
The human body is a very complex biological comprehensive system. Body temperature is an
important data to measure the normality of human life activities. Usually we measure our health by
measuring the temperature of the forehead, cochlea, anus, mouth and axillary. Different part would be
different value, the specific differences refer to the following table:
Measurement part Normal temperature (℃) Normal Fahrenheit (° F)
Anus 36.6～38 97.8～100.4
Oral cavity 35.5～37.5 95.9～99.5
Oxter 34.7～37.3 94.4～99.1
Ear 35.8～38 96.4～100.4

8/ 16
11.2 Normal body temperature range at different ages
A person's body temperature changes at different times of the day and is also affected by other
external conditions, such as age, gender, skin color, and thickness. For the normal temperature range
of different age groups, please refer to the table below:
Age Normal temperature (℃) Normal Fahrenheit (° F)
0 ～2 years old 36.4～38.0 97.5～100.4
3 to 10 years old 36.1～37.8 97.0～100.0
11 to 65 years old 35.9～37.6 96.6～99.7
> 65 years 35.8～37.5 96.4～99.5
Note:
Women's body temperature is different from men's, generally about 0.3 ℃higher than men's,
body temperature during ovulation will rise 0.3 ℃～0.5 ℃than usual.
12. Advice

13.2 Product Maintenance
If you encounter the following problems during use, please follow the instructions in the
maintenance instructions to find a solution. If the problem persists, please contact our customer
service.
1) LCD cannot display the value
If the temperature measurement mode is below 33 ° C or above 43 ° C, the LCD will not display
the data and will display "Lo" or "HI".
2) LCD display message "HI"
Using infrared forehead thermometer, LCD shows "HI", analysis shows that it has exceeded the
measurement range or measured temperature above 43 ℃in human body temperature measurement
mode.
3) LCD display message "Lo"
Using infrared forehead thermometer, the LCD displays the message "Lo", and the analysis shows
that the temperature is below the measurement range or the measurement temperature is lower than

9/ 16
33 ℃in the human body temperature measurement mode.
The information "Lo" or "HI" appears for reference:
Reason for the message "Lo" or "HI"
Temperature measurement result is out of
measurement range
Temperature value is affected by hair and
sweat
Ensure no obstructions during temperature
measurement
Temperature is affected by changes in
airflow
Ensure that the air remains stable during temperature
measurement
The measurement distance is too far Please note that the measurement distance should
not be greater than 5 cm
Enter indoors from outside low or high
temperature
Please wait 15 minutes until the subject's
temperature adapts to the measurement environment
before measuring
