Warm tip:
The measurement results of this unit at any time are
meant to be a reference, it can not replace the medical
diagnosis of professional doctor. If you have any
questions about a temperature result, please consult a
doctor or physician.
1. It is very dangerous for patients to judge and treat on their
only by measurement results, so please be sure toown
doctor's instructions.follow the
Self-judgment may lead to a worsening condition of◆
patient.
2. Please do not touch with your hands or blow infrared
sensor with your mouth.
◆When the infrared sensor is damaged or dirty, it may
cause abnormal measurement results.
3. If there is a temperature difference between the storage
site and the measurement site, please place it at room
temperature (measurement site）for about 30 minutes
before next measurement.
◆May result in incorrect measurement results.
4. Please keep this product out of the reach of children.
◆Children can potentially harm their ears with misuse. If
a child swallows a battery or the transparent cover,
please contact your doctor immediately.
5. When measuring body temperature, please do not get
close to air conditioning.
◆Avoid affecting the measurement accuracy.
6.Before and after use: Use a cotton swab dipped in
75% alcohol to wipe the probe surface. (If you see
stains, fog or water on the infrared sensor glass, please
use a cotton swab dipped in 75% alcohol to clean the
infrared sensor glass gently.)
7. The product suffers mechanical damage.
◆There is a possibility that the measurement is not right.
Warning items
This unit is only used for human body temperature
measurement without use of disease diagnosis; it
cannot be used for emergency and continuous
measurement in surgery.
Parental guidance required for children under
the age of twelve. Children's temperature should
only be measured under the guidance of an
adult.
Patients should not diagnose a disease and/or
get treatment by themselves on the basis of a
measurement result. Please consult a physician.
Children under 12 years of age and those who
cannot express their thoughts must be
supervised during use.
Please do not use this product if you suffer from
otitis external, tympanitis, or other ear diseases.
Warning
◆Do not use toilet paper or facial tissue, they risk
scratching the infrared sensor resulting in incorrect
measurement results.
◆ Avoid cross-infection of ear disease.

8. If the product touches water or is dropped in water,
fully dry before use, especially water on the surface of the
sensor should be cleaned with a cotton swab.

Common sense about body temperature
The comparison of different measurement methods.
The measured values are different if we use different
measurement methods. The WHO provides normal human
body temperature reference values, please see below table
about the specific temperature difference.
The changes in human body temperature
Humans are constant body temperature animals, the body
temperature is basically constant, but it is not totally
changeless, the human body temperature is constantly
changing in a day, the details are as follows:
At night
Lowest Body temperature is lowest because of sleep and
decreasing activity.(below 98.6ºF )
In the morning
Higher From warm bed to the lower temperature room
in the morning, the whole body's muscles get
contractions and produce heat.
At noon
Highest After lunch, the human body reaches the highest
temperature and the body will adjust naturally.
Three or four o’clock in the afternoon
Lower Due to physical exertion, blood sugar decreases.
In the evening
Lowest Due to sun down, the room temperature goes
down.

Product cleaning instructions
In order to ensure precise measurements, it is
recommended to clean the device after each use.
Please use a cotton swab dipped in 75% alcohol to
wipe the thermometer probe and remove any residue
and/or dirt. We recommend you clean the probe for at
least 5 seconds then wipe the other components with a
soft and dry cloth for at least 10 seconds. After cleaning,
please ensure that there is no visible dirt or residue on your
thermometer, Wait 10 minutes before measuring
The device can be cleaned a maximum of 40000 times.

Why do you need to do a cleaning job after each
measurement?
Because infrared temperature uses a highly sensitive
technique to detect the temperature of the target object,
not only will any earwax or dust affect the measurement
accuracy, but it is more likely to cause a bacteria
infection. So we suggest that you cleaning as well as
the diagram shows after each use.

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
a The ISM (industrial, scientific and medical) bands between 0,15 MHz
and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz;
26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The amateur
radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz,
3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz
to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHZ, 21,0
MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and
50,0 MHz to 54,0 MHz.
b The compliance levels in the ISM frequency bands between
150 kHz and 80 MHz and in the frequency range 80 MHz to 2,7
GHz are intended to decrease the likelihood that mobile/portable
communications equipment could cause interference if it is
inadvertently brought into patient areas. For this reason, an
additional factor of 10/3 has been incorporated into the formulae
used in calculating the recommended separation distance for
transmitters in these frequency ranges.
c Field strengths from fixed transmitters, such as base stations for
radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the
location in which the Model PG-IRT1603 Infrared Thermometer is
used exceeds the applicable RF compliance level above, the Model
PG-IRT1603 Infrared Thermometer should be observed to verify
normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the
Model PG-IRT1603 Infrared Thermometer.
d Over the frequency range 150 kHz to 80 MHz, field strengths should
be less than 3 V/m.
