PRECAUTIONS

5 - GB

This thermometer is intended for the periodic
measurement and monitoring of human body
tempera-ture for private use.

INTENDED USE

WHAT IS BODY TEMPERATURE?

Body temperature refers to the internal temperature of
the body (core temperature). ‘Normal’ body tempera-
ture

uctuates over the course of 24 hours. It tends

to be lowest in the early morning and highest in the
late afternoon. Body temperature also varies depend-
ing on the part of the body where the temperature is
measured and also differs with age. Hence, the body
temperature measurement obtained depends on
when and where the temperature is taken and on who
the patient is.

OPERATION OF THE THERMOMETER

Press the ON button [ON].

Insert the probe into the
auditory canal. Straighten
the acoustic meatus by
pulling the ear upwards and
backwards so that the mid-
dle ear is clearly visible.

Children under 1 year:
Make the ear canal straight
by gently pulling the ear
backward.

Children from 1 year and
adults: Make the ear canal
straight by gently pulling the
ear backward and upward.

TEMPERATURE MEASUREMENT –
EAR

In order to ensure accurate measurement, the
patient should

rst rest for 30 minutes in the

same room as the thermometer. Immediately after
exercise or a bath, the temperature may be raised.

7 - GB

For the temperature to
be measured accurately
in the ear canal, the tip of
the probe must be directed
towards the eardrum.

Press the ON button and
wait until you hear a beep.
If no beep is heard, press
and release the ON button
again.

As soon as you hear the
beep, remove the probe
from the auditory canal.
Read the temperature
displayed on the LCD
panel.

36,8 °C / 98,24 °F

34,8 °C / 94,64 °F

• It is advisable to take the temperature in the same

ear, since the values measured in the left and right
ear may be different.

• In the case of patients whose auditory canal is

curved, the temperature values measured may de-
viate owing to anatomical in

uences.

• The ear should not be obstructed, for example by

excessive amounts of ear wax.

To switch from forehead mode back to ear mode,
press MEM for 2 seconds.

NOTE:

8 - GB

TEMPERATURE MEASUREMENT –
FOREHEAD

Always check that the
probe attachment is

xed

onto the thermometer.
Prior to measurement, the
forehead should be free of
perspiration, make-up, etc.

Press the ON button [ON].

Press MEM for 2 seconds,
it will switch to Forehead
Mode.

Place the probe tip with the
attachment on the patient’s
forehead. The recomended
area is on the left-hand side
above the left eye-brow (or
on the opposite side if you
choose the right eyebrow).
Press the ON button (you
will hear a beep) and keep it
pressed down as you slide
the thermometer towards
the left, moving it for at least
three seconds over the
temple. Then remove the
thermometer from the point
of measurement.

In order to ensure accurate measurement, the
patient should

rst rest for 30 minutes in the

same room as the thermometer. Immediately after
exercise or a bath, the temperature may be raised.

9 - GB

• The precise sensing system records the heat emit-

ted naturally through the skin. If the thermometer
is not moved over the temple, the temperature re-
corded may be lower.

• It is advisable to take the temperature 2 - 3 times

and to record the highest value.

• In some patients the forehead temperature may

differ as a result of environmental factors and it is
advisable to take and record your forehead tem-
perature when healthy.

• The measurement of forehead temperature is an

excellent point of reference for recognising raised
body temperature.

• If you are in any doubt about the temperature

measured, please measure it again in the ear and,
for the sake of accuracy, record the highest value.

• Measurement should be conducted in ear mode

only.

• To measure water temperature, keep the probe

at least 1cm (± 0.5 cm) above the surface of the
water. The greater the distance from the surface of
the water, the less accurate the measured values
will be.

Read the temperature
value displayed on the
LCD panel.

MEASURING WATER AND ROOM
TEMPERATURE

NOTE:

Temperatures measured in forehead mode are dis-
played as comparable rectal temperatures.

MEMORY

Press the MEM button.

The

rst memory cell

number (“0”) will then show
the stored temperature (the
last reading).

Press the MEM button
again. Now the reading
before last will be shown.

The other values stored in
the memory can be viewed
by pressing the MEM button
again.

CHANGING THE TEMPERATURE
SCALE

In order to switch over to
Fahrenheit (°F), press the
MEM button and then press
and release the ON button
while the memory cell number
