Measurement

The infrared thermometer can measure the forehead temperature.
Measuring Steps
Step 1: Place the probe between the eyebrows on the forehead, about 5 cm away (do not touch the forehead directly).
Step 2: Gently press the start button, about one second later, the Infrared Thermometer sound prompt, display the measurement results.
If there is no forehead in front, the temperature shows “–“.
Step 3: If there is no operation in 6 seconds, the standby state will be entered. The last measurement result is saved automatically.
Memory View
In the power-on state, long press the start button to enter the memory mode. In memory mode, press the button to view 1-32 groups of memories.
Delete the memory value
When viewing the memory, long press the start button for 2 seconds to clear all memory and display “CLR”.
℃/℉ Switch
Unit switch: In the shutdown state, long press the start button, after full display ℃/℉ will switch, and then you release it.

Fever Prompt Function
The Infrared thermometer has a fever prompt function. When body temperature is over 38.0 ℃ during measurement, the Infrared thermometer will give out a “beep⸺beep ⸺beep” sound in order to remind the person who is under test that he/she gets a fever.
At the same time, the backlight of 3 different colors will indicate the state of temperature: normal, on the high side, or fever.
Green backlight: Below 37.5 ℃, indicating temperature is normal;
Yellow backlight: Between 37.6~38.0℃, indicating temperature is on the high side（should pay attention to the temperature）;
Red backlight: over 38.1℃, indicating fever( should see a doctor as soon as possible).

Common Malfunctions and Solutions

Notes
Note for Forehead Temperature Measurement

• Please measure at the same point when doing forehead temperature measurement, otherwise, the temperature value will have a difference.
• In order to ensure measurement accuracy, there should no hair, sweat, cosmetics, dirt, etc on the forehead when measured.
• Cold coverage, sweating, and other cooling measures on a fever patient’s forehead will make the measurement result lower.
  Users should avoid measurements in this case.

Others

• Please keep the sensor and probe clean before and after measurement;
• The best work environment temperature is between 16℃~35℃
• Don’t use the Infrared thermometer in extreme environments, namely, the temperature is below 16℃ or over 35℃, and humidity is over 85%RH.
• When the person being measured come from a place where the temperature has a big difference from the test environment, he/she should stay in the test environment for at least 5 minutes in order to keep the balance of the body temperature. Otherwise, the measurement result will be influenced.
• If the product is taken from a place where the temperature has a big difference from the test environment, then the product should be placed in the test environment for 20  minutes before measurement.
• Please keep the surrounding environment stable. Don’t measure in the fan, air conditioning vent airflow circle.
• Please avoid using the thermometer under direct sunlight, even outdoors.
• Measurement time interval in the 20s.
• Advise measuring a few minutes later after waking up.
• Do not measure after swimming or bathing or for other reasons not yet completely dry.
• Please do not measure temperature after exercising, bathing, or meal within 30 minutes,
• Before measuring body temperature, do not make any diet, and do not engage in sports activities.
• Do not measure the baby’s temperature during or after breastfeeding.
• The thermometer can take away from the temperature measurement sites, only after the end of the voice prompts to hear the temperature.

Recommendations made three measurements in the following three cases, then take the higher value as the measurement results.

1. Children under three with weakened immune systems (in particular, to judge by children or without fever thermometer);
2. Not yet fully familiar with the use of a thermometer, so each measured temperature value may not be the same;
3. When suspecting the measurement value is low.

Manufacturer’s Declaration of the EUT

Guidance and manufacturer´s declaration ‒ electromagnetic emission ‒ for all EQUIPMENT AND SYSTEMS

Guidance and manufacturer’s declaration ‒ electromagnetic immunity ‒ for all EQUIPMENT and SYSTEMS

Guidance and manufacturer´s declaration ‒ electromagnetic immunity ‒ for EQUIPMENT and SYSTEM that are not LIFE-SUPPORTING

Recommended separation distances between portable and mobile RF communications equipment and the EQUIPMENT or SYSTEM -for EQUIPMENT and SYSTEMS that  are not LIFE-SUPPORTING

Recommended separation distances between portable and mobile RF communications equipment and the Infrared thermometer
The Infrared thermometer is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the Infrared thermometer can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Infrared thermometer as recommended below, according to the maximum output power of the communications equipment
Rated maximum output of the transmitter W	Separation distance according to the frequency of transmitter m
	80 MHz to 800 MHz	800 MHz to 2.7 GHz
0.01	0.12	0.23
0.1	0.38	0.73
1	1.	2.
10	4.	7.
100	12	23
For transmitters rated with a maximum output power not listed above the recommended separation distance d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer. NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies. NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.

About the Temperature

1. the concept of body temperature: the body temperature refers to the body’s internal temperature, the so-called normal body temperature is a healthy person’s body temperature, in accordance with the measurement location, time, different objects may show different results.
2. the normal body temperature, the different parts of the body to measure the results are not the same. Therefore, different parts of the measurement results should not be used to compare with each other. In physical health, multi-test several times, prior to knowing their “normal temperature”.
   NOTE: Product measurement data are used only as an aid to diagnosis.

Maintenance and Attention

The probe of the Infrared thermometer is one of the most important parts, the front probe is mostthe  vulnerable. So be careful when using the measurement, avoiand d damaging the probe.
Please wipe the LCD screen and the shell is gentle with cleaa n soft cloth;
Please place the Infrared thermometer in a cool and dry place, and avoid direct sunlight;

• if a period of time does not plan to use it, please cover the cap and remove the battery;
  Please click the following ways to clean the probe:
  Use a cotton swab or a soft cloth gently wipe with water or alcohol, and do not place this product in water or a liquid immersion;
  Is the packaging products should be stored at a temperature of – 20 ℃ – 50 ℃, with relative humidity not more than 85%, with noncorrosive gases, and a well-ventilated room.
  For a long time (more than 3 months) is not been in use, please remove the battery storage. In addition, the battery is not used for a
  long time, maybe due to battery leakage caused by fault;
  The treatment of waste batteries according to the city of relevant environmental protection regulations for processing;
• if there is in need for repair, can provide the information required for the circuit diagram and maintenance, if there is any doubt from circuit maintenance, contact the manufacturer.
• if you don’t comply with the above note matters and other proper use and lead to machine failure, the company does not assume responsibility for the quality.
  NOTE: Please follow local laws to dispose of waste scrap.
