PLEASE READ THIS MANUAL IN ANY CASE BEFORE USING.

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.

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. 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.
