3.6 Performing Manually Initiated Self-Tests
Upon initial setup, perform a manually initiated Self-Test as described in the following paragraph.
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, release the ON/OFF button. The unit will then
prompt you to “press flashing shock button.” When prompted, press and release the flashing
SHOCK button. The unit will run a series of internal tests, including charge and shock tests. The
manually initiated Self-Test can be aborted by pressing the ON/OFF button again to turn the
unit off. When the Self-Test is complete, the unit will announce its status and power off.
If the Self-Test passes: The unit will announce “UNIT OK” and power off. The unit may then be
immediately used by pressing the ON/OFF button again.
If the Self-Test fails: The unit will announce the symptom. The user should refer to the
“Troubleshooting” section in Chapter 5 of this manual for appropriate action.
Note: Every time the manually initiated Self-Test is run, the unit does an internal shock test.
This test reduces the capacity of the battery pack by one shock.
In addition, every time a battery pack with a non-depleted 9V battery is inserted, the unit runs a
Battery Pack Insertion Self-Test to test the battery pack. When the test is completed, the unit
reports the status of the battery pack and powers off. The unit may then be immediately used
by pressing the ON/OFF button again.
3.7 Storing the DDU-100 AED
The DDU-100 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-100 AED needs servicing – refer to the “Checking Active
Status Indicator” section for more information.
Defibtech recommends storing your AED in an easily accessible location.
