Introduction
Thank you for purchasing the Paryvara TH-1412 Dual Mode Digital forehead
and ear Thermometer. TH-1412 has undergone rigorous clinical tests and has
proven to be safe, reliable and accurate when used in accordance with the
operation manual.
We wanted to make a thermometer that will accompany your child from
infancy to adulthood. That is why the TH-1412 Dual mode infrared
thermometer was designed to measure the body temperature via the subject’s
ear and/or forehead. We recommend that you use the forehead measurement
mode for your children who are < 1 yr. old and move to the eardrum
measurement mode when they are older and more comfortable with a foreign
object in their ear.
Please read the instructions carefully before using the product, and put it in a
safe and secure place for future reference.

1.Features of the Dual mode infrared thermometer TH-1412
The TH-1412 is able to take both forehead and ear temperature
measurements by detecting the infrared heat given off by the respective
areas. Forehead temperature measurements range from 89.6°F - 107.9°F (32
°C –42.2 °C), and eardrum temperature measurements from 32.0°F - 212.0°F
(0 °C- 100 °C).
Convenient and easy to use
Easy mode of operation –No confusing menus and buttons
Can be used anytime –even when your child is asleep
Measures faster than oral thermometer and more comfortable than
rectal thermometer
Ergonomic design
Color coded display for fever
Accurate and quick
Uses latest infra-red scanning technology –precise and immediate
measurements
Safe and hygienic
Unlike traditional thermometers, there is no glass or mercury that could
pose as a potential health hazard. The thermometer is made up of ABS
and TPR plastics, a temperature sensor, an Infrared temperature
measuring element, a microcomputer controlled circuit and a LCD
screen.
BPA and latex free
Memory Recall
Has a Memory Mode that can recall 20 readings to track changes in
temperature.
Convenient Fever warning
When the temperature exceeds 99.5°F/37.5°C, the thermometer will warn the
user that he/she may have a fever by 7 rapid short beeps and the LCD will
flicker. (For normal body temperature, the signal is a long beep)

Warning!
This product is not intended to substitute advice from a physician,
pharmacist, or other licensed health-care professional. You should not
use this product for self-diagnosis or for treating a health problem.
Contact your health-care provider immediately if you suspect that you
have a medical problem.
Operating principle
The infrared temperature sensor collects infrared energy emitted from the
eardrum. After being focused by a lens, the energy is converted into a
temperature reading by the thermopiles and measurement circuits.
2. Precautions - Care and Maintenance
Do not use the thermometer for purposes not specified in this User
Manual. Follow the instructions stated herein and operate the
thermometer carefully when measuring children's temperature.
The device is not designed to be used for new-born babies.
The device is not a continuous monitoring device.
Do not use the thermometer under an ambient temperature higher than
40°C (104°F) or lower than 10°C (50°F), which is beyond the operating
temperature range of the thermometer. To ensure accurate readings,
keep the thermometer under room temperature for more than 30
minutes before use.
Wait at least 10 seconds between every two consecutive readings. Start
a measurement after the measurement symbol is displayed.
Do not touch the tip of the temperature probe, on which a precise
temperature sensor resides.
CAUTION! The sensor is extremely sensitive to dirt and oil. Check
the sensor regularly. The surface should be reflective and
gleaming. If it looks dull and lacklustre, then you need to clean the
sensor before use.

3
To clean the device, use a q-tip cotton swab moistened with alcohol
(70% Isopropyl) to clean the casing and the measuring probe. Please
wait 5-10 minutes for the alcohol to completely evaporate before using
the thermometer.
TH-1412 is not waterproof. Please do not immerse it into the water or
other liquids.
Certain parts of the thermometer are fragile and must be lined precisely
to perform their functions. Do not drop the thermometer or twist the
thermometer sensor. The thermometer is not designed to withstand
intense impact or vibration.
Please do not use the product if the any part of the thermometer,
especially the sensor, shows any sign of damage. Do not attempt to
repair the product. Please contact your distributor immediately.

3. Taking measurements
Forehead mode (Head):
1. Place the thermometer against one side of the forehead
2. Press the “Head” button and move the thermometer slowly across the
forehead whilst holding down the button, you will hear several soft clicks
3. Release the “Head” button and take the thermometer off the forehead
4. Read the temperature from the screen
If you do not move the thermometer across the forehead but take a fixed
point measurement instead, it may result in an incorrect temperature
reading
Ear mode (Ear):
1. Remove the sensor cover off the thermometer
2. Insert the probe inside the ear canal; you can pull the ear a little backwards
for easier access
3. Press the “Ear” button only once, do not hold it down
4. After the beep, take the thermometer out of the ear and read the
temperature from the screen
In order to avoid inaccuracy:
1. Please make sure that there is no dirt on the temperature sensor
2. Please use the thermometer indoors or in an environment where there is no
strong air draft
3. Try to keep the subject stationary.
4. Make sure there isn’t any sweat, water or condensation on the forehead.
5. If TH-1412 is transferred from an environment where the ambient
temperature might be different, please wait 10 minutes before using the
device
6. Before measuring temperature from an ear canal, remove earwax, if any.
Keep the ear canal clean
7. The TH-1412 is not waterproof

4. Changing from Fahrenheit to Celsius
1. To change the temperature from Fahrenheit to Celsius hold onto the
“Ear” button for 8-12 seconds whilst the thermometer is turned off (if
the thermometer is on leave it untouched for 10 seconds for it to
shutdown)
2. The display will change to _ _ _ºF (notice _ _ _ M appears first continue
until you see _ _ _ ºF)
3. Release the “Ear” button as soon as you see _ _ _ ºF
4. Within 5 seconds press the “Ear” button again, the LCD display will
change to _ _ _ ºC
5. Wait for the thermometer to shut down automatically
5. Recalling last temperature readings (Up to 20 readings)
1. Press the “Ear” button until _ _ _M appears
2. Release the button and press “Ear” again straight away to view the last
