Thank you for choosing the iProvèn Dual Mode Digital Infrared Thermometer.
With its unique technology, the Dual Mode Infrared Thermometer DMT-489 can
be used for measuring the body temperature in two dierent ways. You can either
measure the body temperature from the forehead by using the Head-mode or from
the eardrum by using the Ear-mode. The Ear-mode can also be used to measure the
ambient temperature. The Ear mode is suitable for children older than six months and
adults. The Head mode is suitable for people of all ages.
To ensure accurate and stable measurements the thermometer performs a self-test
every time it starts up.
The eardrum and the forehead radiate infrared heat. This thermometer accurately
measures the body temperature as it scans the infrared heat radiated from the forehead and the ears.
Please read the instructions carefully in order to perform measurements in the most
accurate way. Body temperature measurements will NOT be valid or accurate if they
are not performed in accordance with the instructions given in this manual.
Please keep these instructions handy for later reference.
It is our passion
to develop high quality products that can easily be operated by every home user and
provide the best tailored education accompanying the products. We love to help you

with a exible tip such as the iProven DTK-117A.
• The device is not intended to serve as a continuous monitoring device.
• This device is not waterproof. Please keep it away from water or other liquids.
Cleaning and disinfection procedures should follow the instructions specied in
the cleaning section.
• Please do not use the product if the temperature sensor of the thermometer
shows any sign of damage. Do not try to repair the product if it is damaged.
Please contact your supplier.
• The use of this thermometer is not intended to replace appropriate medical
supervision.
• This thermometer consists of high quality, precise parts. The product is not designed to be impact or shock resistant. Avoid dropping the product or subjecting
it to intense shock or vibration.
• Do not twist the thermometer or the temperature sensor.
• Remove the batteries if the thermometer will not be used for longer than three
months.
Warning!
This item is not intended to replace insight from a doctor, pharmacist, or other
licensed health-care expert. You ought not to utilize this item for self-diagnosis or
for dealing with an illness. Get in touch with your health-care supplier quickly if you
think that you have a clinical issue.
Attention:
Electromagnetic interference: this thermomometer contains sensitive electronic
components and should not be used under conditions with electromagnetic interference (such as in the immediate vicinity of mobile phones or microwaves).
Please dispose of the used products and batteries in accordance with local regulations and requirements.
2. Purpose
This thermometer is intended for measuring your own or somebody else’s body
temperature. It can measure the body temperature from the forehead and from the
eardrum. Although the thermometer has undergone clinical tests and is considered
safe and highly accurate, it is intended for non-professional home use only.

4. Operating instructions
4.1 How to get accurate measurements
To ensure accurate measurements, follow these instructions:
1. Please make sure that the temperature sensor is absolutely clean.
2. Please make sure that the device is used in a closed room where there is
no strong breeze or draft.
3. Coverage of the forehead and the ears by hair or a hat will make the forehead
and the ear warmer; therefore make sure that the forehead or the ear has not
been covered during 5 minutes prior to the measurement.
4. Please make sure the forehead is dry and clean before measurement to prevent
the sensor from getting stained.
5. Before measuring the ear temperature, please clean the ear canal.
6. Please be aware that intense emotions and exertion before taking a
measurement can aect the accuracy of the reading.
7. If the thermometer is transferred from one environmental condition to another
that has a dierent ambient temperature, it is suggested to wait at least 30
minutes to get the thermometer adjust itself to the new conditions in order to
get the most accurate reading.
8. Do not hold the thermometer in your hands unnecessarily as it is highly sensitive
to heat. Holding the unit for more than 3 minutes can result in inaccurate
measurements.

4.2 How to use the Head-mode
To measure the body temperature from the forehead, follow these instructions:
1. Point the thermometer sensor toward the temple.
2. Keep some space between the sensor and the skin (approx. 1/4 inch, 0,5 cm).
3. First measure your temple, then the spot between your eyebrows and then the
other temple while holding the head button.
4. Release the head button and take the thermometer o the forehead.
5. Read the temperature from the screen.

4.3 How to use the Ear-mode
To measure the body temperature from the eardrum, follow these instructions:
1. Take o the sensor cover to expose the sensor probe.
2. Pull the ear backward and upward.
3. Gently insert the sensor into the ear canal.
4. Make sure the sensor points in the direction of the eardrum itself.
5. Press the Ear button once.
6. A beep indicates the measurement is successful.
7. Read the temperature from the display.
The most accurate measurement will be obtained when the sensor probe has a direct
view of the eardrum (image 2).

accurate measurement (image 2).
To measure your own temperature, wrap your free hand around the back of your head
and pull your ear upward and backward (image 4).
Aged between 6 and 12 months
Pull the ear backward (image 3).
Aged 1 year and older
Pull the ear upward and backward (image 4).

buttons untouched for 10 seconds.
2. Press and hold the Ear-button for 10 seconds until the display shows “- - -˚C” or
“- - -˚F”.
3. Release the Ear-button.
4. Press the Ear-button once to switch from ˚C to ˚F or from ˚F to ˚C.
5. Wait 5 seconds for the thermometer to save the setting and shut o.
4.6 Automatic power o

shut down.
5. Measurement results
Body temperatures between 36.0˚C and <37.6˚C or 96.8˚F and <99.7˚F are considered
normal body temperatures.
When normal body temperature is measured; one beep will sound and the display will
light green. The measured temperature is shown on the display.
Body temperatures between 37.6˚C <42.2˚C or 99.7˚F <108˚F are considered fever.
When the measurement is in this temperature range, the fever alarm will sound;
7 beeps will sound and the display will light red. The measured temperature is shown
on the display.
5.1 Ear-mode/ Ambient temperature mode
In Ear-mode/ Ambient temperature mode the temperature measurement range is
0.0˚C - 100.0˚C or 32˚F - 212˚F. After any successful measurement between 0.0˚C <
37.6˚C or 32˚F < 99.7˚F one beep will sound and the display will light green. When the
measurement is between 37.6˚C and <100.0˚C or 99,7˚F <212˚F, the fever alarm will
sound; 7 beeps will sound and the display will light red. The measured temperature is
shown on the display.

5.2 Head-mode
In head-mode the temperature measurement range is 0.0˚C - 100.0˚C or 32˚F - 212˚F.
After any measurement between 32˚C and < 37.6˚C or 89.6˚F and < 99.7˚F one beep
will sound and the display will light green. When the measurement is between 37.6˚C
and < 42.2˚ or 99.7˚F and <108˚F, the fever alarm will sound; 7 beeps will sound and
the display will light red. The measured temperature is shown on the display.
5.3 Out-of-range temperatures
Temperature measurements that are outside the measurement ranges will result in
error codes L˚ or H˚ on the display, accompanied by three beeps and the display
lighting red for three seconds.
“ L˚ ”: Measurement is below 32.0˚C or 89.6˚F in Head-mode or below 0.0˚C or 32˚F
in Ear-mode/ Ambient temperature mode. Please make sure you are following the
instructions on how to get accurate measurements.
“ H˚ “: Measurement is exceeding 42.2˚C or 108˚F in Head-mode or over 100.0˚C or
212˚F in Ear-mode / Ambient temperature mode. Please make sure you are following
the instructions on how to get accurate measurements.
6. Cleaning
• Regularly clean the thermometer with a damp cloth.
• Do not use alcohol or benzine for cleaning.
• Prevent the sensor from getting stained by cleaning the ears before using the
Ear-mode.
• Prevent the sensor from getting stained by cleaning and drying before using the
Head-mode.
• Caution: This thermometer is not waterproof! Do not expose this thermometer
to water or any other liquid.
7. Storage
