2. PRECAUTIONS BEFORE USE

THE MYTHERMO BW-CX10 IS PRE-CONFIGURED AT THE FACTORY. THE DEVICE DOES NOT HAVE
TO BE CALIBRATED FOR ACTIVATION.
For reliable and stable results you are advised to leave the MyThermo BW-CX10 at ambient
temperature for 15 to 20 minutes prior to use for each change in environment with a significant
difference in ambient temperature. It is important to wait 1 minute between two readings.
- The protective glass of the lens is the most fragile part of the thermometer.
- Do not touch the glass of the infra-red lens with your fingers.
- Clean the glass with a cotton swab lightly dampened with 70° alcohol.
- Do not put the thermometer in contact with diseased, ulcerated or bruised skin.
- Do not drink hot or cold drinks or do rigorous exercise while your temperature is being taken.

3. INTRODUCTION

The MyThermo BW-CX10 is an infra-red thermometer specially designed to take the body
temperature of children and adults without contact with the human body. The technology
makes it possible to measure temperature on the temporal artery (TA) at a distance of
approximately 2 to 5 cm / 1 to 2 in from the forehead/temple.
The MyThermo BW-CX10 thermometer is precise and instantaneous. It is perfectly adapted to
taking temperature safely. It can be used at home or by healthcare professionals. Nevertheless, it
is essential to use the MyThermo BW-CX10 appropriately in order to obtain a reliable and stable
result. Therefore, you should read the directions and safety instructions carefully before use.

4. OPERATING PRINCIPLES

Each body, solid, liquid or gas, emits energy by radiation with an intensity that is related to its
temperature. The MyThermo BW-CX10 infra-red thermometer measures a person's temperature
by the energy they release. The temperature is taken with the external temperature sensor of
the device which analyses and continuously records ambient temperature. In fact, as soon as
the operator places the thermometer close to the body and turns on the radiation sensor, the
temperature is immediately measured by detection of the infra-red heat emitted by arterial
blood flow. The result of this body temperature measurement is then obtained without
interference of the surrounding temperature.
Benefits of temporal artery temperature (TA) measurement
The arterial infrared temperature can be measured by means of a device placed on the forehead
in the region of the temporal artery.
The thermometer MyThermo BW-CX10 has been designed for the instantaneous measurement
of the temporal/frontal temperature without physical contact with the temporal artery. This
artery being relatively close to the surface of the skin and therefore accessible, the blood
flow is continuous and regular and enables precise temperature measurement. This artery is
connected to the heart by the carotid artery, itself connected directly to the aorta. It is part of

the central arterial system. The efficiency, speed and comfort of taking temperature in this area
of the body make it ideal.
Practical considerations in taking temperature
- For precision and measurement quality, it is essential for each user to be adequately informed
and trained in the temperature-taking technique with a device such as this.
- It is essential to remember that temperature-taking procedures, although basic, should not
be ignored.
- The patient should not carry out intense physical activity before taking their temperature.
- Temperature fluctuations due to physiological factors must be taken into account in the
evaluation of the results:
• The temperature increases by 0,5°C / 0.9°F between 6.00 and 15.00,
• The average female temperature is higher by about 0,2°C / 0.36°F and varies, depending on
their ovarian cycle,
• It increases by 0,5°C / 0.9°F during the first half of the cycle and during the first months of
pregnancy.
- The temperature of a seated person is about 0,3°C - 0,4°C / 0.54°F - 0.52°F lower than that of a
standing person.

How to measure a temperature
A
See figure page 2.
Direct the device towards the FOREHEAD, towards the right temporal region, at a distance
of approximately 2-5 cm / 1-2 in, press the thermometer measurement button, and the
temperature will be displayed instantly.
Constraints
Please observe the following procedure before any temperature measurement, to ensure a
stable and reliable result: -Brush hair away from the forehead.
- If necessary, wipe sweat from the forehead.
- Avoid draughts/any significant air flow (oxygen cannula, air conditioning...).
- Respect a delay of 1 minute between two temperature-takes.
The reliability of the temperature measurement cannot be guaranteed on another
anatomical region (e.g. arm, torso...).
