Precautions for use
This ear and forehead
thermometer receives the infra-red
rays emitted by the skin’s surface
and in the ear drum area. It allows
you to check your child’s
temperature easily. This is how to
use the appliance:
• TET-340 is exclusively dedicated
to take ear or forehead
temperatures. We would like to
re-iterate that this appliance does
not replace the advice of a doctor.
In case of doubt or fever, contact
your doctor.
The simple take of temperature
cannot be considered as a
medical advice, DO NOT modify
the proportion of any drugs
prescribed by your doctor without
seeking medical advice first.
• To ensure the reading is accurate,
the probe and the lens must be
absolutely clean.
• Do not use the thermometer if it
has been dropped or shows any
signs of damage.
• Always place the protection cap
back after use.
• In cases of movement from one
room to another, wait for half an
hour minimum before using the
appliance.
• Wait for half an hour after
physical training, bathing or
eating before measuring
temperature.
• Keep the thermometer out of
reach of children.
• Do not expose the thermometer:
- To any warm sources (radiator,
sun rays, ...)
- To dust or humidity.
• Never immerse the thermometer
in liquid.
• Do not touch the lens with your
fingers.
BODY TEMPERATURE: the normal
human body temperature varies
during the day. It is measured
along a scale of values defined
according to the part of the body
where the temperature is taken:
- Rectal measurement:
36,6°- 37,8°C
- Axillary measurement
(under the arm): 34,7°- 37,3°C
- Oral measurement (in the
mouth) or forehead:
35,5°- 37,5°C
- Ear measurement:
35,8°- 37,8°C
Warning, this appliance is
not suitable for detecting
hypothermia.

Notice:
• For optimal precision, the ear

or a plug.
• Do not use this thermometer with
an ear infection (otitis). Moreover,
if your child has had several ear
infections, the measurement will
be less accurate.
As for all thermometers, slight
variations in temperature may be
displayed one after another:
it is therefore recommended to
take several readings (removing the
thermometer from the ear between
each reading) and take the highest
reading into account.

forehead can be influence by
environmental conditions
because the probe is more sensitive
to perspiration, sebum, physical
activity and environmental
temperature.
It is recommended that you wipe
the forehead before taking a
reading. In case of important
differences or if in any doubt, the
