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.

2
◆Do not subject the thermometer to vibration or impact.
◆The normal body temperature varies from person to person.
Tracking a person's body temperature will help determine
whether they have fever.
◆Do not take body temperature readings within 20 minutes after
you do physical exercises or get excited.
◆Clean the thermometer probe after each use.
◆Do not use the thermometer on newborns or for continuous
temperature monitoring purposes.
◆Do not use the thermometer for purposes that are not specified in
this User’s Manual. Follow the instructions in the "Measurement
Process" chapter and carefully operate the thermometer when
measuring children's temperature.
◆Do not immerse the thermometer in water or other liquid, as it is
not waterproof. 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.
◆Keep the temperature probe clean to make sure accurate readings.
◆Before measuring the temperature from the ear canal, clean the
earwax, if any.
◆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 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
⚫Do not force the temperature probe of the thermometer into an
ear canal. Otherwise, the ear canal may get injured.
⚫Keep the thermometer out of the reach of children.
⚫The result may be inaccurate if you use the overdue thermometer.
⚫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 doctor.
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.
Do not take temperature measurements on body parts other than
forehead and ears. Otherwise, the temperature readings may be
inaccurate.
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.

Body Temperature Basics
• The normal body temperature is a range.
• The normal range varies from person to person and can fluctuate
throughout the day.
• The normal range also varies by body site. Therefore, measurements

5
from different sites should not be compared directly.
To determine if an individual is experiencing an elevated body temperature
and/or having a fever, it is critical to know the individual’s normal body
temperature when he/she is well. Take multiple readings to obtain the
normal body temperature range and note the specific body site measured,
for example: forehead or eardrum temperature.
The normal body temperature range varies slightly 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 (0.5 °F) higher than
men's.
Variation in body temperature
Body Site
Normal Temperature Range
Forehead
34.7°C-37.3°C (94.5°F- 99.1°F)
Eardrum
35.8°C-38.0°C (96.4°F-100.4°F)
Mouth
35.5°C-37.5°C (95.9°F- 99.5°F)
Armpit
34.7°C-37.3°C (94.5°F- 99.1°F)
Rectal
36.6°C-38.0°C (97.9°F-100.4°F)
Normal body temperature
fluctuates throughout the 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 2:00
p.m. and 8:00 p.m. An
individual's body temperature
typically changes by less than
1°C (1.8°F) each day.

Product Description
1) Overview
Infrared Thermometer LS-320 measures the body temperature based on
the infrared energy emitted from the eardrum or the forehead. Users can
quickly get measurement results after properly positioning the temperature
probe in the ear canal or forehead. It can also be used to measure the
surface temperature of object (such as milk and water).
2) Structure
The thermometer consists of a shell, an LCD, a measure button, a beeper,
an infrared temperature sensor, and a Microprocessor.
3) Operating principle
The infrared temperature sensor collects infrared energy emitted by the
eardrum or the skin surface. After being focused by a lens, the energy is
converted into a temperature reading by the thermopiles and measurement
circuits.
4) Intended use
The LS-320 Dual Mode Digital Infrared Thermometer is intended for the
measurement of human body temperatures. The forehead mode is indicated
for use by people of all ages and the eardrum mode is indicated for use by
people above three months old.
5) Contraindications
Do not use the thermometer if the ear is infected with otitis or suppuration.
