    usually once a month. If necessary, you can clean it properly 

    according to the actual soiling of the product. Use a dry soft cloth to 

    clean the non-contact electronic thermometer. If the instrument is 

    extremely dirty, use a cotton cloth or cotton swab with an alcohol 

    content of 70% to clean and disinfect the case and sensor head 

    (the infrared detector cannot be wiped). Be careful not to allow liquid 

    to penetrate the inside of the thermometer.

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. 

If it is lower than 32

℃ 

or higher than 42.9

 in the body measurement 

state, the LCD will not display data, and display "Lo" or "Hi".

1) LCD cannot display the value

Use non-contact electronic body temperature timer, LCD display 

message "HI", indicating that it has exceeded the measurement range 

or the temperature is higher than 42.9

 in human temperature 

measurement mode.

2) LCD display message "Hi"

Using a non-contact electronic body temperature timer, the LCD displays 

the message "Lo", indicating that the measurement temperature is lower 

than the measurement range or the temperature is lower than 32°C in 

the human body temperature measurement mode.

3) LCD display message "Lo"

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, fatness, etc. 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.

· The protective glass outside the LCD frame is very important, and 

   it is also the fragile part of the instrument. Please use it carefully.

· Do not charge non-rechargeable batteries and do not throw them 

   into fire.

· Do not expose the product to the sun, and do not touch the water.
