Safety Precautions
Read the following precautions carefully before using the thermometer.
Attention
• Take care of the temperature probe lens, which is fragile.
• Dispose of used batteries with care. To safeguard 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.
• Normal body temperature varies from person to person. Tracking an
individual’s temperature on a consistent basis will help determine
whether a fever is present.
• Do not take body temperature readings within 20 minutes after you do
physical exercises.
• Clean the thermometer after each use.
Follow these safety precautions carefully when using the
thermometer:
• Do not use the thermometer for continuous temperature monitoring
purposes.
• Do not put the thermometer, which is not waterproof, into water or other
liquid. Clean and disinfect the thermometer as described in “Cleaning
and Disinfection”.
• 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 ensure
accurate readings, keep the thermometer at room temperature for
more than 30 minutes before use.
• Do not use the thermometer at an ambient temperature higher than
40°C (104°F) or lower than 10°C (50°F), which is beyond the operating
temperature range of the thermometer.

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
anaesthetic mixture with air or with oxygen or nitrous oxide
is available.

Body Temperature Basics
Take the body temperature on the forehead. The temperature measured at
different parts of the body may differ slightly.
Body Part Normal Temperature Range*
Forehead 35.8°C–37.8°C/96.4°F–100°F
*The normal body temperature range slightly varies with age and gender.
Generally, newborns or children have higher body temperatures than
adults, and adults have higher body temperatures than the elderly.
Women’s body temperatures are approximately 0.3°C higher than men’s.
Consult your physician regarding body temperatures and acceptable
ranges.

Product Description
1) Overview
Non-contact Infrared Forehead Thermometer
measures human body or object temperature based on
the infrared energy emitted from the forehead or 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 from the forehead. After being focused
by a lens, the energy is converted into a temperature
reading by the thermopiles and measurement circuit.
4) Application scope
The thermometer takes human body temperature for
clinical or household use. It applies to all age groups
and those who are suffering from a fever.
5) Prohibited use
None

object with a distance of 1-5 cm in between, and press the
Measure button.
04. Continuous measurement
1) Hold the Measure button. Move the temperature probe while
keeping the distance between the thermometer and the target
unchanged. The thermometer beeps several times. In this way, the
temperature of different positions of the target can be measured.
2) Release the Measure button. The highest reading during this
measurement period is displayed.
05. After a measurement
1) Repeat the preceding steps to take a new measurement.
2) After each measurement, you can enter the recall mode and query
earlier temperature readings by holding the Mode button. For
details, see “Querying 20 readings” in the preceding table.
3) After each measurement, clean the thermometer with a dry soft
cloth, and put the thermometer in a dry and well-ventilated place.
4) The thermometer automatically powers off if it is not used within
30 seconds.

1) Slide the battery cover off along the marked direction. Put two
AAA batteries correctly into the compartment (batteries included).
2) If the low-battery symbol is displayed on the screen, replace
the batteries.
Ensure that the batteries are installed correctly. Otherwise,
the thermometer may be damaged.
Batteries of a same type should be used. Dispose used batteries
in accordance with local environmental policies.
The thermometer is shipped with batteries installed. Remove the
insulation sheet before use.

Replacing Batteries

Cleaning
1) Clean the temperature probe with a soft cloth. Clean the lens of
the temperature probe with a cotton swab.
2) Wipe the thermometer body with a slightly damp soft cloth, and
gently dry the body with a piece of tissue paper.
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, resulting in inaccurate readings.
Do not clean the thermometer with corrosive cleansers. During the
cleaning process, do not touch the lens using hard objects,
immerse any part of the thermometer into liquid, or allow liquid to
enter the thermometer.
Disinfection
1) Disinfect the thermometer body and the area around the
temperature probe 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.
Maintenance
1) After each use, clean the temperature probe as described in
“Cleaning and Disinfection”.
2) Store the thermometer in a dry, dust-free, and well-ventilated
place. Ensure that the thermometer is not exposed to sunlight.
Ensure that the storage and transportation environments meet
the requirements
3) Check whether safety risks exist on a regular basis.
4) Remove the batteries if the thermometer will not be used for
more than two months.
