Chapter 3 Why the Infrared Forehead Thermometer is Required?

3.1 Quick
With the innovative infrared technology, it can quickly measure the body temperature in non-contact mode.
3.2 Accurate and reliable
By measuring the heat energy emitted from the forehead and calculating the body temperature accordingly, accurate readings can be obtained as long as it is held within a range of 5cm when measuring.
3.3 Simple and easy to use The infrared forehead thermometer is about inductive measurement. It can easily measure body temperature, even for sleeping children.Compared with the rectal thermometer, a non-contact frontal thermometer can reduce the discomfort of children, and it is simpler and more practical than other thermometers in use.
3.4 Safe and hygienic
Contactless measurement can prevent the spread of bacteria;
It is absolutely safe for children and adults;

Chapter 4 Product Installation and Use

4.1Check
Please check the packing case carefully before unpacking. In case of any damage is found, please contact the carrier immediately. Open the package correctly, take out the infrared forehead thermometer and other components from the case with care, and check them one by one against the packing list. When the equipment is moved a different environment, the difference in temperature or humidity may lead to condensation to it, in which case no use is allowed before condensation disappears.

4.2Install or replace batteries
The first step after unpacking is to install the battery. The battery holder is on the back of the infrared forehead thermometer. The battery installation steps are as follows: (1) Open the battery cover. (2) Insert the battery and keep +, – poles of the battery in line with +, – poles of the battery holder. (3) Close the battery cover.

Note: Please use 2 AAA alkaline batteries. Please use batteries if the same type, do not mix used and new batteries. Remove the battery when the thermometer will not be used for a long time. The symbol “ ” appearing on the screen indicates that the battery runs out; please replace the battery before measuring.

4.3 Starting up
Press the “ON/OFF” button, then the backlight of the display comes on, the LCD is shown in full screen and displays the latest group of memory values, the equipment enters the waiting state for measurement; at this time, the backlight goes out, the LED on the forehead keeps flashing, and the equipment gets ready for measurement. If there is no operation for about 60 seconds, the equipment will shut down automatically.

4.4 Placement
Place the thermometer between the eyebrows, at a distance within 5cm from the center of the forehead; In non-contact mode, the blue pilot light will point to the area you are aiming at. If the eyebrow area is covered by hair, sweat or dirt, please clean it in advance to improve the accuracy of the reading. Keep the thermometer and forehead still when
measuring, as movement will negatively affect the temperature reading.

4.5 Mode switch
Toggle the slide switch to select the temperature measurement/calibration mode

4.6 Sound switch settings
In shutdown mode, press and hold the button “Memory”, it first displays “—- M”, which flashes along with the symbol “M”; press and hold the memory button for more than 4 seconds, it displays “—- C + human icon + sound icon”; if the sound is on currently, a “bi” will be heard when entering this mode.

Note:
The equipment will shut down automatically if there is no button press for 60 seconds. It defaults to the current setting after rebooting, while it will save previous settings in case of power failure.

4.7 Body temperature measurement
Toggle the slide switch to the body mode, press the button “ON/OFF measurement” to turn on the forehead thermometer, align the thermometer sensor to the position between eyebrows within 5cm from the forehead, and press the button “ON/OFF measurement”, at this time, the distance focusing light comes on, quickly adjust the appropriate distance (preferably when the focusing light spot is within the pea grain size), when a “bi” is heard about 1S later (no “bi” heard if the sound is disabled), it means that the body temperature has been measured, with the result displayed on the LCD screen.

4.8 Object temperature measurement
Toggle the slide switch to the calibration mode press the button “ON/OFF measurement” to turn on the thermometer, align the thermometer sensor to the object to be measured, and press the button “ON/OFF measurement”, at this time, the distance focusing light comes on, quickly adjust the appropriate distance (preferably when the focusing light spot is within the pea grain size), when a “bi” is heard about 1S later (no “bi” heard if the sound is disabled), it means that the surface temperature has been measured, with the result displayed on the LCD screen.

Note:
When the measured temperature is ＜40.0℃, the LCD backlight is green; when the measured temperature is ≥40.0℃, the LCD backlight is green red and gives a warning with the sound of “Bi”, “Bi”, “Bi”.

4.9 Memory query
Press the button “Memory” to start up the thermometer, the screen displays “—- M” and the symbol “M” flashes. Press the button “Memory” again to display the number of memory groups + M icon, and about 1 second later, show the display memory value + the symbol “M” flashes.

4.10 Memory deletion
In shutdown mode, press and hold the button  “Memory”, the sound setting appears 4 seconds later at first, and keep holding to clear the memory value 8 seconds later, at this time, it shows “CLR + M”, which flashes with the sound of “Bi-Bi-Bi”. After clearing, the equipment will shut down automatically.

4.11 Low battery indicator
When the battery voltage is below 2.60V, only the low-voltage symbol will appear after starting up, and it cannot be used for measurement before the replacement of the battery.

Chapter 5 Special Instructions for Safe Use

You should know the normal body temperature of individuals when they are healthy, which will help you to accurately judge whether they have a fever. To get the normal body temperature, please take more measurements when they are healthy. The normal temperature of children can be as high as 37.7°C or as low as 36.1°C. Please confirm it with a standard electronic thermometer.
The human body can regulate the temperature to keep the normal body temperature within a certain fluctuation range, up to 1°C within a day. Besides, the internal temperature of the human body, i.e. the body core temperature, is different from the surface temperature of the skin, so we cannot simply define what temperature is “normal”, as the body temperature is always in connection with to the measurement site. The level of body temperature is also affected by ambient temperature, age, sleep time, hormonal readiness and physical activity.

Note: Avoid taking the temperature until after 30 minutes has lapsed after 30 minutes in the room (the subject to be measured and the infrared forehead thermometer should be at the same ambient temperature for at least 30 minutes). Keep the infrared forehead thermometer and forehead still when measuring, do not move the thermometer before the last beep is heard. Do not take the baby’s temperature immediately after breastfeeding.

Wait a few minutes before taking the temperature after waking up. Do not eat, drink or do any other physical activity before or during the temperature measurement. If there is a hat on head, please take it off and wait for 10 minutes before taking the temperature. Please clean the dirt or hair on forehead before taking the temperature. Front bangs may cause readings to rise. Wait for 10 minutes before taking the temperature after cleaning the forehead. Please take the temperature in strict accordance with the instructions. Temperature readings may be affected by improper placement.
For the following circumstances, it is recommended to measure the same site three times and take the highest one as the final.1) Newborn babies less than 100 days old. 2) Children under three years old, with low immunity and greatly affected by fever on health. 3) The user learns to use the infrared forehead thermometer for the first time, who has little knowledge about the operation and fails to get stable readings.

If patients intend to take body temperature by their own, we recommend contact measurement.

Chapter 6 Calibration
