Safety Precautions
Read the following precautions carefully before using the
thermometer.
Attention
Take care of the temperature probe lens, which is fragile.
Dispose used batteries with care. To protect the environment, you
are recommended to send the used batteries to a designated
collection point.
Remove the batteries if the thermometer will not be used for more
than two months.
Do not immerse the thermometer in water or expose it to direct
sunlight.
Do not subject the thermometer to vibration or impact.
Do not take body temperature readings within 20 minutes after you
do physical exercises or get excited.
Do not use the thermometer for continuous temperature monitoring
purposes.
Do not immerse the thermometer into water or other liquid. Clean
and disinfect the thermometer as described in the "Cleaning and
Disinfection" chapter.
Do not touch the tip of the temperature probe, on which a precise
temperature sensor resides.
The ambient temperature must not be extremely high or low. To
make sure accurate readings, keep the thermometer under room
temperature for more than 30 minutes before use.
Do not use the thermometer under an ambient temperature higher
than 40°C (104°F) or lower than 10°C (50°F), which is beyond the
3
operating temperature range of the thermometer.
Risk of pollution! The user is recommended to send the overdue
thermometer to local garbage disposal site or send it back to us.
2 AAA batteries of 1.5V are the only replaceable accessories of the
thermometer. Please do not use the batteries of other voltages or
specifications.
Warning
Warning
The thermometer is not intended to diagnose or treat any health
problem or disease. The measurement results are for reference
only.
It is dangerous to make a self-diagnosis or self-treatment based on
the obtained measurement results. For such purposes, please
consult a physician or other medical professionals.
Do not charge an alkaline dry-cell battery or throw it in fire.
Otherwise, the battery may explode.
Do not disassemble the thermometer or attempt to repair it.
Otherwise, the thermometer may be damaged permanently.
During measurement, do not use a mobile phone or any other
device that may cause electromagnetic interference.
Do not use the thermometer in an environment where flammable
anesthetic mixture with air or with oxygen, or nitrous oxide is
available.
Please keep the thermometer out of the reach of children.
The result may be inaccurate if you use the overdue thermometer.

Body Temperature Basics
You can take a body temperature on the forehead, in the ear canal, under
the armpit, in the mouth, or in the anus. The temperature measured at
different parts of the body may differ slightly.
Body Part
Normal Temperature Range
Forehead
36.1°C–37.5°C / 97.0°F–99.5°F
Ear canal
35.8°C–38.0°C / 96.44°F–100.40°F
Mouth
35.5°C–37.5°C / 95.9°F–99.5°F
Armpit
34.7°C–37.3°C / 94.46°F–99.14°F
Anus
36.6°C–38.0°C / 97.88°F–100.40°F
The normal body temperature range slightly varies with age and gender.
Generally, newborns or children have higher body temperature than adults,
and adults have higher body temperature than the elderly. Women's body
temperature are appropriately 0.3°C higher than men's.
Variation in body temperature
Normal body temperature
varies by the time of day and is
also affected by external
factors.
The body temperature of an
individual is the lowest
between 2:00 a.m. and 4:00
a.m. and the highest between
14:00 p.m. and 20:00 p.m. An
individual's body temperature
typically changes by less than
1°C each day.

Product Description
1) Overview
The Infrared Thermometer measures the human body or an object
temperature based on the infrared energy emitted by the forehead or an
object (such as milk and water). You can quickly get measurement results
after pointing the temperature probe to the target.
2) Structure
The thermometer consists of a shell, an LCD, buttons, a beeper, an
infrared temperature sensor, and a Microprocessor.
3) Operating principle
The infrared temperature sensor collects infrared energy emitted by the
forehead. After being focused by a lens, the energy is converted into a
temperature reading by the thermopiles and the measurement circuit.
4) Intended use
The Infrared Thermometer is a non-contact infrared thermometer intended
to obtain the body temperature from the forehead. It may be used by
medical professionals or by consumers in a home environment.
5) Contraindications
None

3. After a measurement
■ After each measurement, clean the thermometer with a dry soft cloth,
and put the thermometer in a dry and well-ventilated place.
■ The thermometer automatically powers off if it is not used in 10
seconds.
Notes:
(1) The thermometer is suitable for an indoor environment without
strong air convection between the thermometer and the target. For
example, winds from a fan, an air-conditioner, or a heater.
(2) Do not hold the thermometer for a long time, because it is sensitive to
the ambient temperature.
(3) Make sure the sense head is free of foreign matters before use;
(4) Make sure the forehead has no sweat and no hairs covered before
measure the forehead temperature; otherwise, the result could be
incorrect;
(5) No intense emotion or strenuous exercises before measuring;
Replacing Batteries
1) Slide the battery cover off along the marked direction. Insert the two
17
AAA batteries into the compartment correctly.
2) If the low-battery symbol is displayed on the screen, replace the
batteries.
Make sure that the batteries are installed correctly. Otherwise, the
thermometer may be damaged.
Batteries of a same type should be used. Dispose the used batteries
in accordance with the local environmental policies.
The thermometer is provided with batteries that were installed in
the factory. When you start to use it in the first time, open the
battery cover, then remove the insulating piece.
Cleaning and Disinfection
Cleaning
Recommended detergents:
＊ Medical detergents;
＊ Home use mild detergents;
Cleaning steps:
1) Take the batteries out before cleaning.
2) Clean the temperature with a soft cloth. Clean the lens of the
18
temperature probe with a cotton swab.
3) Wipe the thermometer body with a slightly damp soft cloth.
Keep water off the lens during the cleaning process. Otherwise, the
lens may be damaged.
The lens may be scratched if it is cleaned with a piece of tissue paper,
which might result in inaccurate readings.
Do not clean the thermometer with corrosive cleansers. During the
cleaning process, do not touch the lens using hard objects, do not immerse
any part of the thermometer into liquid, or allow liquid to penetrate the
thermometer.
Disinfection
Recommended disinfectants:
＊ Isopropyl alcohol solution (concentration: 70%)
＊ Medicinal alcohol (concentration: 75%)
＊ Sodium hypochlorite solution (concentration: 3%)
Disinfecting steps:
1) Wet the clean soft cloth with a small quantity of disinfectant, wipe
the thermometer and quickly dry it.
19
2) Disinfect the thermometer body with a cloth slightly moistened with
75% medical alcohol.
Do not use hot steam or ultraviolet radiation for disinfection.
Otherwise, the thermometer may be damaged or quickly aged.
Clean and disinfect the thermometer under the temperature of
+10℃~+40℃(50℉-104℉), the relative humidity of 15%~85%RH (no
condensation) and the barometric pressure of 86kPa~106kPa.
Maintenance
Preventive inspection & maintenance period
1) Ensure the safety of thermometer, and check whether it has potential
safety hazards in normal use each week, e.g. whether the lens is
broken, the shell has cracks and the sensing head is polluted. Do not
use the thermometer with potential safety hazard. Clean the
thermometer if not used for a long time.
2) Store the thermometer in a dry, dust-free, and well-ventilated place.
Make sure that the thermometer is not exposed to sunlight. Make sure
that the storage and transportation environments meet the
requirements.
3) Remove the batteries if the thermometer will not be used for more
than two months.
