Please contact your doctor. • Carefully read and follow the enclosed instructions to ensure accurate temperature readings. • Please keep still during measurement. • This thermometer is used for taking temperatures through oral, rectal or underarm. Do not attempt to take temperatures at other sites, such as in the ear, as it may result in false readings and may lead to injury. • Store the thermometer out of the reach of children. Do not allow children to take their temperatures unattended. Children may injure themselves when attempting to take temperatures without supervision. • Do not leave the battery, battery cover or probe cover where children can reach them. Children may swallow them. If a child accidentally swallows the battery, battery cover or probe cover, please contact a doctor immediately. • Do not attempt measurements when the thermometer is wet as inaccurate readings may result. • Please dispose of waste in accordance with national regulations on environmental protection. WARNING ! -1- Product Structure Package Include Important Safety Notes • Do not bite the thermometer. Doing so may lead to breakage and/or injury. • Do not share the thermometer among individuals. • Do not attempt to disassemble or repair the thermometer. Doing so may result in inaccurate readings. • Do not attempt to incinerate the battery. It may burst. • Pay attention to polarity (+ / ‒) when replacing the battery. Failure to do so may lead to fluid leakage, heat generation or bursting, resulting in damage to the unit. • Do not use the thermometer in places where strong static electricity or electromagnetic fields are present. Doing so may lead to inaccurate readings and may contribute to instrument failure. • Do not force the thermometer into the rectum. Stop insertion and abort the measurement when pain is present. Failure to do so may lead to injury. • Do not attempt rectal measurements on persons with rectal disorders. Doing so may aggravate or worsen the disorder. • Do not step on the unit or the hard case. • Do not attempt to disinfect the probe sensor of the thermometer by immersing in alcohol or in hot water (water over 50°C). • Failure to use a probe cover may lead to bacteria and viral infection. • The ME EQUIPMENT or ME SYSTEM is suitable for home healthcare environments. • Don't near active HF surgical equipment and the RF shielded room of an ME system for magnetic resonance imaging, where the intensity of EM disturbances is high. • Do not use the thermometer to measure anything other than human body temperatures. • Avoid taking the temperature until after 30 minutes has lapsed after exercise, bathing or eating/drinking. • Dispose of the thermometer when its service life is reached. Follow local regulations regarding the disposal of such product. • When the performance changes (such as: inaccurate temperature measurement, inaccurate temperature measurement or abnormal display), please stop using it immediately and contact the after-sales service personnel in time. • Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the this device, including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment could result. CAUTION ! GENERAL SAFETY PRECAUTIONS ! -2- • If the product will not be used for a long time, please remove the battery and place it properly. • When ambient temperature is 40, The time from minimum storage temperature to use is at least 1 hour; The time from maximum storage temperature is at least 2 hour. -3- Symbol Definition 1. Press the measure button to turn on the thermometer (with a short beep). Three color backlight will be displayed, and 2. Place the thermometer in an appropriate position, oral, underarm or rectal. 3. The measurement takes about 10 seconds, after five times beeps, you can remove the thermometer from the site, and take the reading. displays for 1 second, and then shows the last temperature value for about 3 seconds（it will not be displayed if it’s for the first time use ）, and then " ---- " displays. Now you can start the measure. NOTES: 1) T indicates a temperature reading: 32°C≤T≤37.3°C(89.6°F≤T≤99.14°F):There will be 5 beeps and displayed in green. 37.3°C<T≤38.7°C(99.14°F<T≤101.66°F):There will be 5 beeps and displayed in orange, which is a warning that you may have a low fever. 38.7°C<T≤42.9°C(101.66<T≤109.22°F):There will be 5 beeps and displayed in red, which is a warning that you may have a high fever. Intended use Contraindication How to Use The Digital Thermometer is designed as reusable battery-operated electronic device, and intended for the measurement of oral, armpit and rectal temperature for people of all ages.
