4.7 Internal safety discharge
An internal safety discharge ensures that the stored energy is discharged within the
device every time a defibrillation shock was not delivered correctly. An internal dis-
charge is performed if:
– after the defibrillation energy has been charged, the heart rate changes into a
non shockable rhythm
– the shock has not been delivered within the 20 seconds following the end of de-
fibrillation energy charging
– an electrode error is detected
– the battery voltage is insufficient
– the device is defective
– the device is switched off before the shock is delivered.
4.8 Finishing the therapy
• Switch off the device once the therapy has been completed (press and hold the
green button for approx. 3 seconds).
• Disconnect the electrode cable.
• Carefully peel the pads off the patient’s skin (see Fig. 4.13 Removing the adhesive
pads).
• Recycle the disposable pads immediately after use to keep them from being reused by
mistake (hospital waste).

If the device's behaviour differs from the description given in this user guide, the
device is defective and must be repaired.
• 5 minutes after the device has been switched off, the number of shocks delivered
as well as the time elapsed since the device was turned on, are reset to zero.
• If the device is turned off for less than 5 minutes, all data is stored (even if the bat-
tery is removed), and the device continues to count the number of shocks deliv-
ered, to measure the time elapsed since the device was turned on, and to store
intervention events from the point at which the device was turned off.
