communications equipment and the CLETEF-786 Infrared Thermometer.
The CLETEF-786 Infrared Thermometer is intended for use in an
electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the CLETEF-786 Infrared
Thermometer can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications
equipment (transmitters) and the CLETEF-786 Infrared Thermometer as
recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in meters (m) can be estimated using
the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.

The Advantages of Clever Choice Duo
TM
Dual mode (forehead temperature and ear temperature)
Thanks to dual mode design, you are free to take body temperature
by detecting the infrared heat given off by the forehead or eardrum,
The forehead temperature measurement range is from 89.6
℉
to
108.0
℉
（
32
℃
to 42.2
℃
）
.The ear temperature measurement range
is from 32.0
℉
to 212.0
℉
（
0
℃
to 100.0
℃
）
.
The product consists of ABS plastics, temperature sensor, Infrared
temperature measuring element, microcomputer controlled circuit,
LCD , backlight and buzzer.
Convenient for use
Special ergonomic design to facilitate operation.
No inconvenience would be caused to your daily life. It’s available
for measurement when your children’s sleeping.
It provides comfortable user experience compared with anus
thermometer for children, rapid reading and simple operation
compared with mouth thermometer.
Memory recall
A maximum of 20 previous readings is available to help you track the
changes of your body temperature.
Safe and hygienic
Compared to mercury thermometer, there is no danger of
breaking the glass or swallowing mercury.
It is completely safe for children to use.
Fever warning
After a reading, the backlight will appear green, orange, or red to
indicate presence and severity of a fever. When the temperature
is more than or equal to 38.0°C/100.4 , there will be 6 short
double and half beeps and the reading will flicker with orange
backlight for 5 seconds. This indicates that you may have a fever.
Please consult your doctor if you are not sure. If fever is worse,
the backlight will appear red.
Extensive clinical data of hospital
The cooperation with designated hospitals is subjected to precise
clinical verification, with the support of extensive clinical data and
professional medical experts.
2
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. (Ear temperature mode should not be used for
children below 3 months)
Operating principle
The infrared temperature sensor detects infrared energy emitted by
the eardrum. A built-in lens focuses the collected energy, which is
converted into a temperature reading by the thermopiles and
measurement circuits.
2. Necessary Safety Instructions
The device is not for use with newborn babies.
The device is not a continuous monitoring device.
CLETEF-786 is not waterproof. Please do not douse it with water
or other liquids. Cleaning and disinfection procedure shall be in
comply with the instructions specified in “cleaning and storage”
Please do not use the product if the temperature sensor or the
infrared thermometer shows any sign of damage. Do not try to
repair the product if it is damaged. Please contact Simple
Diagnostics Customer Service.
CLETEF-786 consists of precision parts. No replacement shall
be provided for damage due to intense shock or vibration. Do not
twist the infrared thermometer and the temperature sensor.

Interference may occur near
equipment marked with the
following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic is
affected by absorption and reflection from structures, objects and people.
a. 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 CLETEF-786 Infrared
Thermometer is used exceeds the applicable RF compliance level above, the
CLETEF-786 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 CLETEF-786 Infrared
Thermometer.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3 V/m.

read temperature value about every 0.5 seconds and then shows the
maximum temperature value at the end.
5.How to Use Ear Mode
1. Gently remove the sensor/probe cover to reveal the ear probe.
2. Insert the ear probe into the ear canal. Ensure that the sensor is
pointer towards the eardrum.
3. Press and release the
Ear
button. The temperature will be displayed
on the screen instantly. You can take another measurement when the
backlight is off.

Note:
Children under 1 year: Pull their ear straight back.
Children aged 1 year to adult: Pull the ear up and back.
To Avoid Inaccurate Readings:
1.
Make sure that there is no dirt in or on the temperature sensor
2.
Use the device indoors, or with no strong winds.
3.
Make sure there is no sweat on the forehead.
4.
Make sure the ear canal is clean.
5.
Hold still and keep calm during measurement.

8. Cleaning and Disinfection
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 age quickly.
9. Maintenance
1.
After each use, clean the temperature probe as described in
