Caution Do not place this equipment out of the reach of children, who may inadvertently damage it. 3 The lens of the probe is a fragile part of the infrared thermometer. Please protect it carefully. Do not throw away used batteries at will, because waste batteries pose an environment hazard. Its recommended to send the waste batteries to a designated collection point for disposal, so as to prevent environmental pollution. If the thermometer is not going to be used for more than 2months, remove the batteries and keep the thermometer properly. Do not immerse the thermometer into water or put it under sunlight for direct exposure. The thermometer should be avoided from strong impact or vibration, otherwise it may be damaged. A normal body temperature varies from person to person. Keeping track of a persons body temperature changes will help determine whether a person has a fever. Do not take a measurement if you just exercise or are emotionally excited. You should rest for about 20 minutes before taking a measurement. The probe should be cleaned after each use. Do not use the thermometer on newborns or for continuous temperature monitoring purposes. Do not use the thermometer for other than its intended purposes. Please follow the measuring instructions in the manual and be careful when measuring a childs temperature. Do not immerse the thermometer into water or any other liquid. For cleaning and disinfecting methods, please follow instructions in urinating, etc., even in the absence of fever. Cleaning and Disinfection. Do not directly touch the top of the probe, because there is a precise temperature sensor on the top. Keep the probe clean to ensure accurate measurement results. If the ear canal is dirty, first clean the ear canal with a cotton swab before taking a measurement. The temperature of the measuring environment should not be too cold or too hot. If you enter the measuring environment from storage environment, you should stay in the measuring environment for over 30 minutes before taking a measurement. Do not take a measurement in an environment with temperature higher than 40 (104) or lower than 10

(50.0), because the normal operating temperature of the thermometer is exceeded under such environment. When the thermometer reaches the expiration of its service life, throwing it away at will poses an environment hazard. Its recommended to send it to your local collection point or handling or send it back to the manufacturer for Recycling Replaceable accessories of the thermometer include two 1.5V AAA batteries. Do not use batteries of different voltage or Do not use the thermometer if there are signs of damage on the measuring sensor or on the instrument itself. If damaged, do not attempt to repair the instrument! Please contact the dealer. It is dangerous to make a self-diagnosis or self-treatment based on the obtained measurement results. For such purposes, please consult a doctor. When the performance changes (such as: inaccurate measurement or abnormal display), please stop using it immediately and contact the sales service personnel in time. When the ambient temperature is less than 10C, please take the device to the place where the ambient temperature is between 10C~40C at least When the ambient temperature is higher than 40C, please take 1 hour;

In general, the temperature Keep dry Fragile, handle with care RoHS RoHS mark Non-ionizing electromagnetic radiation Common Knowledge of Human 1)Body Temperature Generally, human body temperature is measured via the following main sites: forehead, cochlea, armpit, oral cavity and anus, etc., because temperature readings obtained from the above sites are the closest to human body temperature. However, there exist certain differences for actual temperature readings measured from different sites. The specific differences are as follows:

Measuring site Forehead temperature Ear temperature Oral temperature 6 Normal temperature range 36.1C37.5C / 97.0F99.5F 35.8C38.0C / 96.44F100.40F 35.5C37.5C / 95.9F99.5F of a newborn baby or child is higher than that of an adult, the temperature of an adult is higher than that of an elder, and the temperature of a female is about 0.3 higher than that of a male. Body Temperature Day-Night Variation Graph Human body temperature fluctuates over time during a day and is affected by external factors. The same person has the lowest temperature during 02~04 a.m. and has the highest temperature during 14~20 p.m. Under normal circumstances, the day-night temperature difference is not greater than 1. Product Introduction 1) Overview Infrared thermometer is a measuring instrument which utilizes infrared receiver 4) Intended Uses The infrared thermometer takes human body temperature via the eardrum or forehead.
