Safety Precautions
Before using the thermometer, please carefully read the
following precautions:
Caution
This product cannot be used to replace a monitoring instrument
that continuously monitors the body temperature.
The temperature probe is a sensitive component of the infrared
thermometer, and keep it carefully.
Do not discard the exhausted battery at will; take it to a specified
environmental protection place for processing to avoid
environmental pollution.
Remove the battery if the product has not been used for more
than two months.
Never put the product into water or under the sun; otherwise,
the product may be damaged or suffer accelerated aging.
Do not acutely vibrate the product or collide it with other things;
otherwise, it may be damaged.
The normal body temperature varies from person to person. You
are advised to record daily measurement values and use them
as reference values to determine whether you have a fever.
Your body temperature rises when you are taking exercise or
have emotional outbursts. In this case, you are not advised to
measure your body temperature.After exercise, take a
20-minutes rest before making measurement.

2
After using the product, clean it, and keep it in a dust-free, dry,
and ventilated place.
When using the product, note the safety precautions below:
The product is not waterproof, and do not put it into water or
other liquid. For the cleaning and disinfection method, see
Cleaning and Disinfection.
Do not directly contact the top of the temperature probe, where
there is a precise temperature sensor at the top.
Keep the temperature probe clean, and clear away dirt or
cerumen, which may affect the measurement result.
When there is dirt in the auditory meatus, use a cotton ball to
clean it before making measurement.
The measurement environmental temperature should not be too
low or too high. After the instrument enters the measurement
environment from the storage environment, make measurement
30 minutes later.
Do not make measurement at a temperature higher than 40C
(104F) or lower than 10C (50.0F) because the temperature in
this case is beyond the normal working temperature of the
thermometer.
Do not use the thermometer for unexpected purposes, and
follow the safety precautions when making measurement for a
child.

3
Warning
Warning
During measurement, do not forcibly insert the temperature
probe into the auditory meatus, which may hurt the auditory
meatus.
The thermometer is not a diagnostic instrument, and the
measurement result is only used as reference for a doctor.
It is risky to perform auto-diagnosis and treatment according to
the measurement result; follow the doctor's diagnosis.
Do not refit the product without permission of the manufacturer,
which may damage the product or cause safety problems.
The thermometer can be used cooperatively with a dedicated
earcap. When no earcap is used, you are advised to use the
thermometer for only one person, to avoid cross infection.
Do not charge or put the common alkaline dry battery into the
fire, to avoid a risk of explosion.
Do not disassemble or repair the thermometer if you are not
professional, to avoid causing irreparable damage.
During measurement, do not use a mobile phone or another
device with strong electromagnetic field interference.
Do not use the thermometer in an environment where there is a
gas mixture of inflammable anesthetizing gas and air, or a gas
mixture of oxygen and nitrous oxide.

4
Do not use the thermometer to make measurement for any part
of the body except the ear; the measurement result may be
incorrect.
Keep out of reach of children.

Product Introduction
(1) Overview
The JPD-FR302 infrared thermometer (referred to as thermometer
in the following) is a measurement instrument that uses the infrared
receiving principle to measure the temperature in the tympanic
membrane of the earhole. You only need to insert the temperature
probe into the earhole and place it at the correct position, and press
the measurement key to quickly and correctly measure the ear
temperature.
(2) Product Structure
This product mainly consists of a casing, a liquid crystal display, a
press key, a buzzer, an infrared sensor, and a microprocessor.
(3) Measurement Principle
The infrared thermometer uses the infrared temperature sensor to
receive infrared energy emitted by heat generated in the tympanic
membrane of the earhole. The energy penetrates through the lens
and becomes concentrated, and is further converted into a
temperature value by using the thermopile and measurement circuit.

6
(4) Expected Usage
This product intends to be used by a medical department or a family
to measure the body temperature.
(5) Scope of Application
The temperature of a measured object is displayed by measuring
thermal radiation of the thermal radiation of the earhole.
(6) Contraindications
Do not use this instrument for an individual having diseases such as
otitis media and ear fester.

Measurement Method
1. Precautions before Use
1) This thermometer is applicable to indoor environments. There
should be no strong cross-ventilation between the instrument
and a measured object during measurement (for example, a fan,
an air-conditioner, and a heater blow against each other).
2) This thermometer is sensitive to the environment temperature;
do not hold the thermometer for a long time.
3) Keep the temperature probe clean and unblocked before using
the thermometer.
4) Before measuring the temperature of the ear, keep the auditory
meatus clean; otherwise, the measurement result may be
incorrect.

9
5) Do not have emotional outbursts or take acute exercise before
measurement.
6) Make measurement 30 minutes later after taking the
thermometer into the measurement environment, if there is a
temperature difference between the storage environment and
the measurement environment.
7) The measured individual is advised to take a more than 10
minutes rest before measurement, if the individual enters the
measurement environment from an environment and there is a
temperature difference between the two.
2. How to Measure the Temperature of the Ear
1) Cover the temperature probe with an earcap
Put the earcap into the earcap box, open the top
cover of the earcap box, pull out one earcap,
place it at the hole on the top, and keep it flat,
and press downwards the temperature probe of
the thermometer in the transparent film direction
in the middle of the earcap until the earcap fully
covers the temperature probe. Take out the
temperature probe and close the earcap box cover.
2) Insert the temperature probe into the auditory meatus and place
it at the correct position (shown in the following figure)
When making measurement for an adult, lift the ear slightly upwards;
when making measurement for a child, lift the ear slightly backwards

10
to make the auditory meatus straight and the temperature probe aim
at the tympanic membrane direction.
3) When measuring the temperature of the ear, press and release
the measurement key. The buzzer beeps once, and the display
screen displays the measurement value about 1s later.
3. End of Measurement

11
1) After the measurement is completed, in the power-off state, long
press the measurement key for more than 4s but less than 6s to
enter the memory query mode, in which you can view previous
measurement records. For detailed operations, see Query of 20
Groups of Memory Data in the following table.
2) After the measurement is completed, use a dry, soft cloth to
wipe the thermometer, and keep the thermometer in a dry and
ventilated place.
3) The thermometer is automatically powered off if no key is
operated for 10s.
