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

As soon as your measurement is finished, open the app on your smart phone to transfer the readings. Note: On the matched smart phone, Bluetooth must be enabled.2. You can view your temperature readings in the app.
Memory Mode1. The Memory Mode can be accessed either in forehead mode or object mode: When the thermometer has been turned on and followed by Figure 2/5 or finished testing, press the Setting Button. The letter M will appear in the lower left corner of the display. (See Figure 6)2. The thermometer will automatically memorize the last 30 temperature readings. Each memory also records the measurement mode icon. Each time the Setting Button is pressed, the screen displays past readings that correspond with a number 1-30. The number 1 reflects the most recent reading, while the number 30 reveals the oldest reading stored in memory.(See Figure 7)3. In the memory mode, mark or mark will not change. The user can press the Test Button to take new measurements.
Care And Cleaning1. The probe window must be kept clean, dry, and undamaged at all times to ensure accurate readings. The accuracy of temperature readings can be affected by damage to the probe window, or the presence of dirt, fingerprints, earwax, dust and other soiling compounds on the probe window. Degraded sensors can degrade performance or cause other problems.2. For cleaning 1) Soak a clean soft cloth in drinking water,wring it out,and then wipe the thermometer(including probe) no less than 3 times 2) Visual or use magnifying glass to observe the thermometer have no visible dirt and stains ,then use another clean soft cloth to wipe the thermometer residue water 3) Put the thermometer in the original packaging.3.For disinfection 1) Soak a clean soft cloth in drinking water,wring it out,and then wipe the thermometer(including probe) no less than 3 times 2) Visual or use magnifying glass to observe the thermometer have no visible dirt and stains ,then use another clean soft cloth to wipe the thermometer residue water 3) Using a clean soft cloth dipped in 70% medical alcohol,wipe the probe for 3 Times,each time 1 minute. 4) Using a clean cotton swab dipped in 70% medical alcohol,wipe the sensor window 3 times 5) Wait at least 10 minutes to let the alcohol volatilization and put it in the original packaging.4.

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.
