2. Purpose of the Device
This thermometer is intended to be used to measure the body temperature of hu-
mans who are a minimum of six months old when using the ear measuring function
and suitable for all ages when using the head function. It measures the body tem-
perature based on heat radiating from the eardrum or from the forehead. Although
this thermometer has undergone extensive clinical tests and is considered safe and
highly accurate, it is intended for non- professional home use only.

3. Setup instructions
3.1 First use
Before using this product for the rst time, the battery protection tab must be removed.
Remove this plastic tab by gently pulling it out of the battery compartment.
3.2 Replacing the Batteries
1. Release the battery cover by gently sliding it down.
2. Remove the battery cover.
3. Replace both AAA- batteries according to the polarity marked on the battery
chamber.
4. Replace the battery cover and make sure all of the pins of the cover are aligned
with the gaps.
5. Close the battery cover by sliding it up until you hear a click.
4. Operating instructions
4.1 Precautions for Accurate Measurements
Carefully follow these instructions to ensure accurate temperature readings:
• Ensure that the thermometer lens is clean.
• If the thermometer is transferred to a new location with a dierent room
temperature, wait at least 30 minutes before using it.
This will allow the thermometer to adjust to the new conditions and prepare it to
give the most accurate readings.
• Ensure that the ears are clean. Earwax inuences the accuracy of the measurement.
• Utilize the thermometer in a closed room where there is no strong breeze or draft.
• Ear or head coverage by hair or a hat will make the ear warmer; ensure that the ear
or the head has not been covered for 5 minutes prior to the measurement.
• Please be aware that intense emotions and strenuous physical exertion before
taking a measurement can aect the accuracy of the reading.
• Avoid holding the thermometer in your hands any longer than necessary, since it is
highly sensitive to heat. Holding the unit for more than three minutes can result in
inaccurate measurements.
4.2 How to Correctly Perform an Ear Measurement
Image 1 Image 2 Image 3 Image 4

- 7 -
1. Remove the sensor cap to expose the sensor probe.
2. For adults, pull the ear backward and upward with your free hand to straighten
the ear canal (image 1).
3. Gently insert the sensor into the ear canal.
4. Ensure that the sensor is aimed directly toward the eardrum (image 2).
5. If the ear canal is not straightened, inaccurate readings may result (image 3).
6. For children between 6 and 12 months old, pull the outer ear straightbackward
(image 4).
7. Press the button once to take the measurement.
8. A beep indicates that the measurement has been taken and the thermometer
may be removed from the ear.
9. Look at the display to read the temperature.
10. Clean the sensor and cover it again with the sensor cap.
4.3 How to Correctly Perform a Head Measurement
NOTE: The forehead measurement is an indicative reading. The measured forehead
temperature can uctuate up to 1.0 ˚F/ 0,5˚C from your actual body temperature.
Please be aware of the factors that inuence the accuracy as described in the section
‘Precautions for Accurate Measurements’.
Always check if the lens is clean.
Always make sure the user and the thermometer will have been in the same
room for at least 30 minutes prior to the measurement.
To perform a head measurement:
1. Keep or put the sensor cap in place;
2. Aim the sensor at the temple and start holding the button;
3. Move the sensor across the forehead to the other temple.
4. Release the button as soon as the sensor is at the other temple.
Tip: Touch the skin lightly but do not press the sensor too hard to the skin as this
may give inaccurate measurement results. Visit www.iproven.com/489 to watch the
instruction video.
PLEASE READ BEFORE YOU START:

4.4 Memory Retrieval
Each time a successful measurement is performed, the measurement data is stored
in the thermometer memory. The memory of this thermometer has a capacity of 20
measurements. To retrieve stored measurements follow these instructions:
1. Ensure that the thermometer is turned o. If the display is not dark, leave the
buttons untouched for 10 seconds.
2. Hold the Ear button for 4 seconds, and release the button when the display
shows“- - -M”
3. The last measurement will appear and the M sign will blink.
4. Press the ear button again to see the previous measurement; repeat as needed
to view earlier measurements.
5. The retrieved information includes the measured temperature and the type of
temperature taken (whether an ear, head or room measurement)
4.5 Switch Between Fahrenheit and Celcius
1. Ensure that the thermometer is turned o. If the display is not completely dark,
leave the buttons untouched for 10 seconds.
2. Press and hold the ear button for 7 seconds until the display shows “- - - ˚C” or
“- -- ˚F”.
3. Release the ear button and immediately press it again to switch the temperature
scale.
4. Wait 5 seconds for the thermometer to save the settings and shut itself down
before you use it again.
4.6 Automatic Power-o
If the buttons are left untouched for 10 seconds, the thermometer will automatically
shut down.
5. Measurement Results
5.1 Room Temperature Measurement
This device may be used to measure room temperatures between 32 ˚F and 89.5 ˚F, as
well as 108 ˚F to 212 ˚F. This corresponds to 0.0 ˚C to 32 ˚C and 42.2 ˚C to 99.9 ˚C.
To measure the room temperature press the ear button once while remaining at least
3 ft / 1 meter space between the sensor and any object.
5.2 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 beeps and the display lighting
red for three seconds. “L ˚”indicates that the measurement is below 32 ˚F, or 0 ˚C.
“H ˚” indicates a measurement exceeding 212 ˚F, or 100.0 ˚C.

5.3 Interpreting the Measurement Results
6. Cleaning
• Regularly clean the thermometer sensor with a damp cloth, moistened slightly
with water.
• If you desire disinfecting the sensor probe you can do so by using a disinfecting
wipe or a cotton ball damped with a disinfectant.
• You can prevent the sensor from getting stained by ensuring the ear canals are
clean.
Caution: This thermometer is not waterproof! Do not immerse or expose it
to water or any other liquid other than using a slightly damp cloth.
7. Storage
• Store this thermometer at room temperature. The most accurate temperature
measurement is obtained when the thermometer and the user have both been
exposed to the same ambient temperature for at least 30 minutes.
• Always store this thermometer in the enclosed soft case to prevent it from
collecting dust or being exposed to bacteria.
• If your thermometer is likely to remain idle for more than 90 days, we
recommend you remove the batteries and store them separately.

8. Troubleshooting
• Error: Display shows “ ER1” + backlight is red + 3 beeps sound
Meaning: The room temperature has dropped below 10 ˚C/ 50 ˚F or exceeded 40
˚C/ 104˚ ˚F. Desired action: Store the thermometer at room temperature.
• Error: Display shows “ ERC”+ backlight is red + 3 beeps sound
Meaning: EEPROM data reading error or the correcting process is not nished.
Desired action: Contact your supplier.
• Error: Display shows low-voltage signal (not blinking) Meaning: The battery
voltage is below 2.61V±2%. Desired action: Replace the batteries according to the
