3.6 Performing Manually Initiated Self-Tests
Upon initial setup, perform a manual Self-Test as described below:
Note that a manual Self-Test consumes approximately one shock’s worth of energy, and
will therefore reduce the usable capacity of the battery.
To perform a manual Self-Test, begin with the unit powered off. Press and hold the ON/OFF
button until the unit announces that it is performing a Self-Test – this should take approximately
5 seconds. Once you hear the announcement, you may release the button.
The unit will run a series of internal tests, including charge and shock tests. When the Self-Test
is done, the unit will announce its status and power off. You may also manually terminate the
Self-Test before it completes by pressing the ON/OFF button again, which will abort the Self-
Test and power off the unit.
In addition, whenever a battery pack with a non-depleted 9V battery is inserted, the unit will
perform a Battery Pack Insertion Self-Test, announce the status of the battery pack, and power
off.
Note that Self-Test shocks are internally dissipated so that no voltage is ever present at
the pads.
Once the unit has powered off, it is immediately ready to treat a patient, unless errors were
detected which rendered the unit inoperable.
3.7 Storing the DDU-120 AED
The DDU-120 AED (preferably with pads attached) should be stored in environmental
conditions within range of the specifications - refer to the “Environmental” section of
“Technical Specifications”. The unit should also be stored so that the Active Status Indicator
can be readily seen.
The Active Status Indicator should periodically blink with a green light. If it blinks with a red
light or does not blink at all, the DDU-120 AED needs servicing – refer to the “Checking Active
Status Indicator” section for more information.
Defibtech recommends storing your AED in an easily accessible location.
