Warning PLEASE READ THIS MANUAL IN ANY CASE BEFORE USING. ENGLISH PRECAUTIONS The ear thermometer must be inserted correctly to obtain correct temperature measurement. Be sure to consult a physician if you feel something is wrong with you. Do NOT judge only by whether you have a fever or not. 1. Very gently and carefully insert the probe into the ear. 2. Avoid using the ear thermometer if the ear is inflamed. 3.
ENGLISH 8. Do NOT boil the probe. 9. Do NOT use the ear thermometer if it operates irregularly or shows sings of malfunction. 10.Do NOT use thinner or benzene for cleaning the ear thermometer. 11.When using the ear thermometer after storage at low temperature, place it in a warm place for 5 to 10 minutes before use. 12.Keep the ear thermometer out of reach the children. 13.Wipe the ear thermometer clean before storing. About Ear Thermometers All objects radiate heat.
Caution ENGLISH 1. A person’s left and right ear canals are not necessarily symmetrical. This may cause different measurement results. Always take temperature in the same ear. 2. A soiled probe window will result in inaccurate measurement. Be sure to check that the probe is clean before use. 3. Body temperature rises after vigorous exercise, a bath or shower, or eating. Wait at least 30 minutes before measuring temperature. 4.
If the ambient temperature is 35 ˚C or higher: To prevent the ear thermometer from measuring the ambient temperature, make sure that the power is turned off, then hold the switch pressed for at least 3 seconds. Still holding the switch pressed, insert the probe into the ear, then release the switch. Caution 1. Small children must not operate this instrument, and it must be kept out of their reach. Be sure that body temperature is measured by an adult. 2.

ENGLISH Questions and Answers Q1: Why is temperature measured in the ear different from the measurement result under the armpit or in the mouth or rectum? A1: Temperatures at different parts of body may differ. Compare the measurement in question with normal temperature previously taken in the same ear. Q2: Temperature differs each time I measure.
