1.2 Knowing Body Temperature
Normal human body temperature is a rang, not a fixed value. It fluctuates throughout the day; generally,
lowest in the morning and highest at sunset. It also tends to decrease with the age -infant has higher
temperature than adult .
As well , different sites (oral , axilla , rectum and ear) have different temperature -generally speaking, ear
temperature is close to oral but higher about 0.5 °C than axillary temperature.
Human body temperature is controlled and adjusted by the hypothalamus in the brain and the blood
flowing through hypothalamus also flows through ear drum. Then measuring ear temperature can best
reflect the body temperature than other sites. Our Infrared Thermometer uses infrared technology to
measure infrared energy emied from the ear drum and surrounding ssue ; then coverts into the
temperature value-safely, conveniently and precisely measure the ear temperature for you.

Before You Use The Infrared thermometer
Using our Infrared thermometer to take ear temperature, the normalhuman body temperature range is
35.5~38.0 °C (96.4~100.4°F )
Table of normal human body temperature range by age:
Age
0-2 years
3-10 years
11-65 years
>65 years
Range( °C )
36.4-38.0°C
36.1-37.8°C
35.9-37.6°C
35.8-37.5°C
Range( °F )
97.5-100.4°F
97.0-100.4°F
96.6-99.7°F
96.4-99.5°F
However, the normal range is also different from person to person. To determine your and your family
members’ normal temperature range is very important. It can be done easily by using our Infrared Ear
Thermometer. Please pracce to take temperatures on yourself and your healthy family members to
determine their normal temperature ranges.

1.3 Important Safety Notes
Please read through the instrucon manual before using the thermometer; as
proper technique is crical for taking accurate temperatures. The performance of
the thermometer may be adversely affected withimproper usage.
Do not use the thermometer outside the operang ambient temperature
of 10 ° C (50 ° F)~40 ° C(104 ° F).
Do not use the thermometer outside the operang ambient humidity up to 95%RH.
Do not use the thermometer when the ear canal is wet, or when the person
is suffering from ear diseases.
Earwax and obstrucons will affect the accuracy of the thermometer.
Sideway sleeping gesture will cause the ear temperature to rise, please avoid it.
The thermometer is calibrated and does not require re-calibraon if used
according to the instrucons.

The measured temperatures may be different in the different ear side. Please
measure the same ear to help ensure the accurate measurement.
Aer shower or exercise, the body temperature will rise.
Do not insert the probe into the ear canal with excessive force.
When the baery symbol" "appears, it means low baery, please replace the
new baery.
This thermometer is intended for household use only. The use of this thermometer
is not intended as a substute for physician' s consultaon.

1.2 Usage Method
Please make sure the cleanness of the opcal glass inside the probe. You can use a coon swap to clean
the opcal glass; if moistened with alcohol, waing and restarng aer 5 minutes, otherwise the result of
measurement will be too low.
Measuring method (ear):
Perform an ear tug to straighten the ear canal. This gives the thermometer a clear view of the eardrum.

If the ear temperature is over 38.0 °C ,it is fever.
FEVER: over 38.0°C

Operaon Instrucons
While tugging the ear, fit the probe snugly into the ear canal as far as possible and press the measurement
buon. Release it, when you hear the Beep.
Children under 1 year:
Pull the ear straight back.
Children aged 1 year to adult
Pull the ear up and back.

When the LCD displays " " symbol, you can measure again. If you don’t press any buon within one
minute, the thermometer will shut down automacally.
Note: It is recommended that you take three temperatures measurements in the sameear
under the following circumstances. If they are different, use the highest reading.
Infants in the first 3 months of life.
Children under three years old who have a condion such as a compromised immune system and for
whom the presence or absence of fever is crical.
When you are first learning to use the ear thermometer unl you are comfortable with the technique and
are gaining consistent reading.
Replacing The Baery:
When the display appears" "symbol, meaning low baery, please replacethe baery with a new one.
1. Prepare a lithium cell, type CR2032.
2. Remove the baery cover (B-6).
3. Be sure the <+> up and replace the new baery.
4. Put back the baery cover.

Important: As with any type of thermometer, slight temperature
variaons (±0.2-0.3°C/±0.3-0.5°F) can happen, if consecuve
measurements are taken.

1.2 Usage Method
Measuring method (forehead):
LCT-300 can measure forehead temperature (aiming at forehead at a distance about 1 cm) without
touching the skin. It is suitable to checking many person quickly and safely. We suggest that using
forehead measurement to check temperature at first. If the person’s forehead temperature is higher
than 37℃, switch to ear measurement to double check his temperature.
Press (A-4) to turn on and the thermometer is default as ear funcon.
To measure forehead temperature, please press (A-3) and " " will appear on the top le corner of LCD
display. Aiming the probe at forehead or temporal about 1cm distance from skin, press (B-5) to get the
forehead temperature. You can switch to measure ear temperature by pressing (A-3) again and " "
disappears; then it return to ear funcon.
Since forehead (temporal) temperature is easily affected by the ambient, if you take forehead
temperature and get a reading higher than 37.0°C (98.6°F) , it is beer to double check if the client has a
fever by switching to ear funcon and measuring ear temperature.
Our forehead measurement is really no touching the skin and only 1 secondmeasuring me.
