Charging the physiokey
The physiokey indicates the current battery power during operation with a symbol (here illustra-
ted on the display after starting the default settings):
Battery power:
Bright = Residual power
Dark = Consumed power
Before the battery power is too low for ongoing operation of the physiokey, an acoustic signal
can be heard. If the battery power is low, the physiokey cannot be started. In this case, connect
it to the charger.
The scope of delivery includes a battery charger with micro USB connector. To charge the physio-
key, plug the charger in a suitable power socket and connect it with the physiokey. The device has
to be switched off. It cannot be used during charging. During charging, the screen illustrated be-
low is displayed. After a short time, the display is switched off during charging to save power and
to accelerate the charging process. For information on the charging process, press the "Home"
button to wake up the display.
The charger socket has to be protected against the ingress of fluids. For this reason, always close
the charger socket with the included USB plug after charging.
