3. INTENDED USE OF THE DEVICE
The device is intended solely for private, non-commercial use to measure the body
temperature of persons in the ear or forehead and to measure the surface temperature of
objects to the extent specified by the technical and operating parameters and functions
of the device, safety and user instructions and external influences of the operating
environment.
Warning!
The use of the device does not replace professional examination with qualified medical
personnel.
Before first use
Please read this instruction manual carefully before using it for the first time, because
correct temperature measurement is only possible when handling the unit correctly.
Because of external influences, it is otherwise likely that the measured values will not be
correct.
This manual describes the steps in measuring temperature with this thermometer and
contains important and useful tips for a reliable body temperature. Carefully store these
instructions for use.
The thermometer is designed to measure the body temperature measured by infrared
technology. Compared with conventional thermometers, it has the advantage of measuring
faster. In addition, it is no longer necessary to measure body temperature in the oral cavity,
rectum or underarm. By inserting it into the ear canal to measure the ear drum temperature
or by attaching it to the forehead, the thermometer can reliably measure body temperature.
However, since the measurement is faster than with conventional thermometers, and
because the ear drum and face are on the surface of the body, it is necessary to carefully
observe certain measuring conditions so that the measured temperature is accurate.
The thermometer is a high quality product for measuring human body temperature in the
ear and forehead. It is ideal for measuring temperature in children (recommended for 6
months), but can also be used by adults.
When properly used, the thermometer guarantees fast, accurate and comfortable
measurement of body temperature.
We wish you all good health!

Advantages of the thermometer
Two measurement methods: measurement from ear and forehead
1. Thermometer measures body temperature (Body Temp mode) from ear and forehead.
Depending on what you prefer, you can choose a place for temperature measurement.
2. The thermometer also measures the surface temperature of objects (Surface mode).
High measurement accuracy with the latest measurement sensor technology the latest
generation of measurement sensors guarantees a very high accuracy of temperature
measurement when measured from ear and forehead.
When measuring the temperature of objects, the thermometer only needs to focus on the
desired object.
Due to infrared technology is very fast.
The measuring sensor captures the infrared radiation emanating from the drum,
respectively. from the face of the forehead and report the measurement result at a time.
Simple operation
The instrument is operated very easily and safely with the buttons. Use the power button
(memory data recall) to turn the device on or off and also to start the measurement.
Principle of operation
Each object produces a certain amount of energy of infrared radiation. The energy of the
radiation emitted and its wavelength depends on the surface temperature. The human body
at a temperature in the range of 35.5 - 43.0 ° C emits infrared rays with a wavelength of
5 - 13 μm. Based on this fact, we can accurately calculate the body temperature from the
difference between body temperature and temperature at the face surface.
Advantages of the thermometer
The thermometer measures Body Temperature from ear or forehead. Depending on what
you prefer, you can choose a place to measure body temperature.
General body temperature information
The human body regulates the body temperature to the desired value - it is up to 1 °C
throughout the day. The temperature in the body (core body temperature) and surface
temperature on the skin show different values. So there really is no “normal” body
temperature - it always depends on
measurement site. Body temperature is also affected by external temperature, age, stress,
sleep time, hormones and physical activity. While the classic glass thermometer and digital
thermometer directly measure body temperature, measurement of body core temperature
through infrared radiation of the body is measured in the ear and forehead. This can also
differ slightly from the temperature measured in the rectum, the oral cavity, or in the armpit
with a digital thermometer even if measured correctly.
During life, the average body temperature can fall by up to 0.5 °C.
Overview of measured values (°C):
Status Ear/Face
Low temperature < 35,7
Normal temperature 35,8 – 36,9
Increased temperature 37,0 – 37,5
Light Fever 37,6 – 38,0
Mild fever 38,1 – 38,5
High Fever 38,6 – 39,4
Very high fever 39,5 – 42,0
• The temperature measured in the ear may differ from the temperature measured on
the forehead as the face temperature affects the external influences more than the
temperature of the ear drum.
• The same is true when compared to measuring body temperature in the rectum, the oral
cavity, or the armpit.
• Repeated measurements of consecutive measurements generally have slightly different
results, however, they move within the tolerance of the measurement.

Preparation
The thermometer measures body temperature in mode Body temp from both
the head and the ear. You can use both measurement methods to measure
your own body temperature (own measurement), as well as for measuring the
body temperature of another person (foreign measurement). To measure body
temperature, the thermometer must be set to body temperature. If after switching
mode Body temp surface indicator is not lit when the thermometer is turned on,
press MODE to switch the thermometer to Body temp.
In surface temperature measurement mode, the temperature sensor measures
the surface temperature of various items (milk in baby bottle, building materials,
etc.).
1. If there is no battery in the device, open the battery compartment cover and
connect a 9 volt battery (not supplied) to the contacts. Observe the correct
polarity as + and - on the battery and the battery compartment contacts. After
connecting the battery, insert it into the storage compartment and close the

2 Before measuring, you must turn on the thermometer. Press the on/off
button. Turning on the display, displaying all segments at a moment when the
thermometer is switched on for the first time for a long time, the mode name
and the temperature that is being measured are displayed (if the temperature
sensor is in the body temperature mode and is not aimed at the human body,
Lo (temperature below 32 ° C), if the temperature of the objects is in the mode,
the measured temperature is displayed and the thermometer beeps.
Subsequently, the thermometer is prepared for further measurement.
In order to achieve accurate results, it is important to follow these guidelines:
Please ensure that the thermometer and the person whose temperature is to
be measured are in a room at room temperature for at least 30 minutes before
measuring. To get maximum accuracy for the next measurement, wait for 30
seconds between each measurement.
After sleeping, it is recommended to wait a few minutes to measure the
temperature.
Do not measure immediately after showering, swimming etc. when the ear or
face is wet.
Do not eat, drink or inject before measuring.
Do not measure the temperature during or after breastfeeding.Befoore
measuring, remove the hair and wipe the seat from the ear and forehead.
Release the key and move the thermometer to a greater distance until the final
beep sounds and the measured temperature is displayed.
In the following situations, it is recommended to perform three temperature
measurements and consider the highest value as the result of the
measurement:
- in children younger than 3 years with a weakened immune system (especially
when it is critical whether or not the child has a fever);
- Users who are not yet familiar with the device until they reach constant
measured values.
- when a low measured value is suspected.
If you have doubts about the measured temperature and the temperature
does not match the patient’s feel, we recommend repeating the measurement
after a few minutes. Please also observe the cleaning instructions. We also
recommend that you measure the temperature by another independent method
or seek a doctor.
- The measured value memory is not displayed in the surface temperature
measurement mode.

switches off automatically.
Important information for measuring the temperature in the ear:
• Temperature values may be different for each ear. Therefore, please always
measure the temperature from the same ear.
• If you were lying on one ear, the temperature may be measured shortly
afterwards in this ear.
• Do not measure the temperature from the ear in which an inflammatory disease
occurs, even after an ear injury (eg drum damage) or is in the healing phase
after surgery. If drugs are administered in the ear, they should not be measured
from that ear. In these cases, consult your physician beforehand.
