TURNING ON THE THERMOMETER

The device must be installed and put into operation
in accordance with the instructions in this manual.
To get help concerning usage or maintenance plea-
se contact your dealer or the manufacturer.
An unexpected operating condition or an incidence
which has worsened the health condition or could
have worsened the health condition should be
reported to the manufacturer immediately.
To turn on the thermometer, push the ON/OFF-button;
a short signalling tone [beep] indicates «thermome-
ter ON.» A so-called LCD-test automatically takes
place to check the display. Then a «L» and a flashing
«°C» appear on the upper right of the display, if the
ambient temperature is less than 32°C. Now the ther-
mometer is ready for use.

USING THE THERMOMETER

During a measurement, the temperature is displayed
continuously and the «°C» symbol flashes. If the sig-
nalling tone sounds (beep-beep-beep-beep 10 times)
and the «°C» no longer flashes the measurement is
completed (the measured increase in temperature is
now less than 0,1 °C in 15 seconds).
To extend the lifetime of the battery, turn off the ther-
mometer after usage by pressing the ON/OFF-button
briefly. Otherwise the thermometer will automatically
turn off after about 10 minutes.

MEMORY OF MEASURED VALUES

When turning the thermometer on, the temperature
of the last measurement will be displayed. After 3
seconds, this value will disappear and the thermome-
ter will switch to the normal measurement mode.
Then the stored value is erased.

CLEANING AND DISINFECTING

For cleaning of the instrument please use isopropyl
alcohol (70%). For disinfecting wipe the instrument
completely with Antifect Liquid (please obey 5 min.
work-in-time).

The device is NOT waterproof! 

CHANGE OF BATTERY

As soon as the symbol "     " appears on the display,
the battery is weary and a new battery has to be in-
serted. Open the cover of the battery compartment
and insert the new battery with "+"symbol facing
upwards.
