...............28 The DET-3010b 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 LCD. The infrared forehead thermometer is intended for the intermittent measurement of human body temperature from the skin surface of forehead by people of all ages. When properly used, it will quickly assess your temperature in an accurate manner. Please read all instructions carefully and thoroughly before using this product. Do not allow children to take their temperatures unsupervised, Warning:

1. There is no gender or age limitation for using infrared forehead thermometer. 2. Do not touch the temperature probe with hands . 3. Use of this Forehead thermometer is not intended as a substitute for consultation with your physician. 4. some parts are small enough to be swallowed. 5. Never immerse this device in water or other liquids(not waterproof). 6. Do not modify this equipment without authorization of manufacturer. 7. Do not expose the thermometer to temperature extremes

(below -25/-13 or over 55/131) nor excessive humidity (>95%RH). 8. Keep the battery away from children. 9.Remove battery from the device when not in operation for a long time. 1 2 Product Description LCD Display Introduction 1. Probe 2. START Button 3.

Please see the tinghe first use. Forehead Mode Object Mode 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 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 to measure the object temperature. Infrared 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 Beep Hint When the testing is done, it will sound one short beep. the body such as oral, rectal and underarm. Vital Organs Memory Mode The machine can store up to 30 sets of measurements. Each memory also records the measurement results date/time/mode. When the data exceeds 30 sets, the coverage starts from the earliest data.

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 temperature when 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 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. 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 a baby. 9. Do not take temperatures with this thermometer near places that are very hot, such as fireplaces and stoves. 10. The probe window of the thermometer is the most delicate part of 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. 8 10 7 9 before taking a reading.
