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. Do NOT use the ear thermometer if the main body is damaged (for example, the probe window is broken). The continuous use of damaged

unit may cause injury, an improper result or serious danger.
Contact a physician immediately if someone swallows broken pieces.
Caution
1. The body temperature measured in the ear may differ from the measurement under the armpit or in the mouth or rectum. Therefore, they cannot merely be compared. Take the temperature periodically to determine the reading with this instrument when body temperature is normal, then use that as the basis for comparison with any measurement taken when you suspect a fever.
2. Do NOT use this thermometer for measurements other than body temperature. The ear thermometer will be damaged if it is used to measure the temperature of bath, refrigerators etc.
3. Do NOT immerse the ear thermometer in Water and do NOT spill chemical solvents on the unit.
4. Do NOT drop the ear thermometer and do NOT expose the ear thermometer to heavy shock. As the ear thermometer is not shock­protected construction.
5. Do NOT bend the ear thermometer.
6. Do NOT disassemble the unit, do not make any modifications and do not touch the circuitry.
7. Do NOT store the unit under the direct sunlight, NOT at the high temperature and NOT at a high degree of humidity or dust.

About Ear Thermometers
All objects radiate heat. To measure body temperature, this ear thermometer uses an infrared sensor incorporated in its probe to detect the heat radiated from the eardrum and its periphery. In general the ear canal (external auditory canal) of an infant is relatively straight. As we grow older, it takes on some curvature, as shown in Fig. 2. It is important to point the probe window of the ear thermometer toward the eardrum and its periphery inside the ear. To straighten the ear canal, gently pull on the outer ear in the direction of the rear of the head, as shown in Fig. 3. Each ear canal has a slightly different shape. Be sure to check it before measurement. And then insert the prove straight, as shown in Fig. 4.
