For a reset, the TEST button needs to be pressed longer than 10 seconds. It is
recommended to perform a reset each time a fault is indicated. If the fault indication
persists, the battery is defective and cannot be used any more.
Automatic shut-down of the display (protection from deep discharging)
To protect the battery from deep discharging, the display shuts down automatically. The imminent
shut-down is indicated by running lights, with each of the 5 LEDs blinking in sequence for about 1
second. The display reactivates automatically when the battery is being charged.
Battery conditioning
The battery should be conditioned with the internal battery conditioning program or with the optional
battery charging unit ASU 3000 every month. As the ASU 3000 is a specially designed battery
charging unit that has a definite conditioning mechanism, it is advisable to use it to condition the
battery. Furthermore the conditioning cycle will last about twenty-one hours if performed in the
defibrillator and only five hours in the ASU 3000.
N
OTE
Since the battery will be discharged in the course of the program and the program takes several hours to
complete, a second charged battery must be available to ensure that the defibrillator is ready for use.
The conditioning program can only be run when the defibrillator is connected to the patient monitor
and the monitor, in turn, is connected to the power line.
Start of Conditioning
•
Connect the monitor-defibrillator system to the power line.
•
Turn the defibrillator on.
