You can take oral, rectal or vaginal measurements, but you should
always take the measurements in the same place in a cycle� We
recommend taking the measurement under your tongue with your
mouth closed�
The thermometer should not be changed during the cycle� If you
change the thermometer during the cycle, you must also note it as
a disruption, just like a change to the place of measurement� For this
cycle, a reliable evaluation is then no longer guaranteed�
1� Remove the protective cap from the measur-
ing tip� In order to switch on the thermome-
ter, press the on/off/measure button� A short
acoustic signal confirms that the device is
switched on� The thermometer first conducts
a self-test for approx� 2 seconds� All seg-
ments of the display are visible during this
time�
