Figure 3-2: Ba ery charge status display
The charge status of the internal and external ba ery is displayed in the top le -hand area of the medin-NC3®
screen (Figure 3-2).
A full ba ery is shown with a symbol with  ve bars. As soon as only two bars remain, the ba ery symbol is shown
in red and the medin-NC3® should be connected to the mains soon. As soon as there is only one bar le , the
ba ery alarm is triggered.

When the medin-NC3® is running on ba ery power, an alarm is sounded when the internal ba ery is low. If this
happens it is essen al that the device be connected to an external power source without delay.
Please note:
If the medin-NC3® ba ery is completely depleted, it can only be recharged very slowly which greatly increases the
recharging  me (up to 5 hours). In addi on, the ba ery will be damaged by this exhaus on and will need to be
replaced sooner. Since the ba ery of the medin-NC3® also recharges while switched o , it is recommended that
the medin-NC3® be regularly charged during longer periods of storage.

external ba ery. A er inser ng the new external ba ery, close the ba ery compartment securely.
A en on:
The external ba ery may not be replaced during opera on of the medin-NC3®.
3.2.4. Power supply unit
The power supply unit of the medin-NC3® may only be used according to its imprinted input and output power.

Warning:
If the medin-NC3® is not connected to the mains, the internal ba ery also discharges while the device is switched
o , that is, if the medin-NC3® is to later be used on rechargeable ba ery power, it must be recharged beforehand.
If the alarm Ba ery low – Connect power supply unit does not disappear despite connec ng the power supply
unit and dele ng the alarm text (e.g. by triggering a push no  ca on or a higher-priority alarm (red)), there may
be a defect of the medin-NC3®. Contact a service technician and do not use this medin-NC3® for the  me being.
