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.

Reference temperature

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

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:

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.

Advice

The protective sheet outside the LCD frame is very important, it is also the fragile part of the meter, please use it carefully.

•  Do not charge non-rechargeable batteries and do not throw them into fire.
•  Please do not expose this product to the sun, and do not touch the water.

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  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
