Please read all instructions carefully and thoroughly before using this product.

Indication for Use: The infrared forehead thermometer is a non-contact infrared thermometer intended for the intermittent measurement of human body temperature from forehead at a distance of 1~5cm by people of all ages. This thermometer is reusable for home use and clinical use and can be reused by many people. The DET-3019b infrared forehead thermometer is specifically designed for safe use on the forehead. The Infrared Forehead Thermometer is a device capable of measuring people’s body temperature by detecting the intensity of infrared light emitted from the forehead. It converts the measured heat into a temperature reading displayed on the LED display. When properly used, it will quickly assess your temperature in an accurate manner.

The thermometer has been designed for practical use. It’s not meant to replace a visit to the doctor. Please also remember to compare the measurement result to your regular body temperature. Please see the Illustration For Use section to learn how to measure the body temperature.The object mode shows the actual, unadjusted surface temperatures, which is different from the body temperature. It can help you to monitor if the object temperature is suitable for the baby or patient, for example the baby’s milk. Please see the Illustration For Use section to learn how to measure the object temperature.There are each 30 sets memories for forehead and object measurements. Each memory also records the measurement mode icon.If the object is too far away from the probe, the temperature will not be measured until the probe is moved within the measured range. If the APP is successfully connected to the machine,the Bluetooth sign will always be on, otherwise it will keep flashing.Please see the Setting to learn how to change between Celsius and Fahrenheit. Please see the Setting to learn how to change between Chinese and English. The thermometer will broadcast the result after finishing measurement.The thermometer can turn on or off sound. Please see the Illustration For Use.



Forehead Thermometer AdvantagesInfrared Forehead Thermometer measures core body temperature, which is the temperature of a body’s vital organs. (See Figure 1) This thermometer is designed to measure the temperature of the skin surface over the temporal artery, a major artery of the head. The temporal artery is connected to the heart via the carotid artery, directly leading from the aorta, the main trunk of the arterial system. It offers constant blood flow. Therefore, body temperature changes are reflected sooner in the forehead than they are in other parts of the body such as oral, rectal and underarm.Vital Organs

Temperature Taking Hints

Temperature Taking Hints

To ensure that the reading always reflects the body temperature accurately, you need to take account of the following factors which may affect an accurate reading. 1. It is important to know each individual’s normal temperaturewhen they are well. This is the only way to accurately diagnose a fever. To determine normal temperature, take multiple readings when healthy. Re-measure with a standard digital thermometer for confirmation. 2. Users must be inside for 30 minutes before taking a measurement. Note: Users and the thermometer should be in the same ambient temperature for at least 10 minutes before taking a reading. 3. Users should not drink, eat, or be physically active such as bathing, showering, shampooing and hair drying before/while taking the measurement. Remove hat and hair and wait 10 minutes before taking a reading. 4. Oils or cosmetics on the forehead may give a lower temperature reading than the actual one. Remove dirt from the forehead before taking a measurement. Wait at least 10 minutes after washing the forehead area before taking a reading.9

5. Holding a hand on the forehead for any length of time will affect the temperature reading.6. Do not take temperature over scar tissue, open sores or abrasions. 7. Do not use the thermometer on a perspiring or sweating forehead,as this may affect the reading. 8. Don’t take a measurement while or immediately after nursing ababy. 9. Do not take temperatures with this thermometer near places thatare very hot, such as fireplaces and stoves. 10. The probe window of the thermometer is the most delicate partof the device. Do not touch the probe window. The accuracy of the reading may be affected if the probe window is damaged or dirty. 11. If the thermometer is stored in a significantly different environment than testing location, place it in the testing location for approximately 30 minutes prior to use. 12. It is not intended for use in the oxygen rich environment and presence of flammable anesthetic mixture with air, oxygen or nitrous oxide.10

Illustration For UseTo measure forehead temperature: 1. Press the Test Button, The display is activated to show allsegments. After self-checking Figure 2 appears on the display screen with voice, so you can start a new measurement. 2. Aim the thermometer at the center of the forehead with a distance less than 5cm (See figure 3) and then press the Test Button. Note: Do not remove the thermometer from the forehead before hearing voice. Note2:If the object to be tested is too far from the probe, a prompt will appear(See figure 4). 3. Read the temperature on the display. 4. Press and hold Test Button to turn off.

Electromagnetic Compatibility Information Electromagnetic Compatibility InformationTable 3 continuedNOTE 1At 80 MHz and 800 MHz, 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.a The ISM(industrial, scientific and medical) bands between 0,15 MHz and 80 MHz are 6,765 MHzto6,795 MHz;13,553 MHz to 13,567 MHZ;26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz,3,5 MHz to 4,0 MHz,5,3 MHz to 5,4 MHz,7 MHz to 7,3 MHz,10,1 MHz to 10,15 MHz,14 MHz to 14,2 MHz,18,07 MHz to 18,17 MHz,21,0MHz to 21,4MHz,24,89 MHz to 24,99 MHz,28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0 MHZ.b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2,7 GHz are intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 has been incorporated into the formulae used in calculating the recommended separation distance for transmitters in these frequency ranges.c Field strengths from fixed transmitters, such as base stations for radio(cellular/ cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device.d Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
