5.2.3 Running a Manually Initiated Self-Test
The DDU-100 AED runs a Power-On Self-Test every time the unit is powered up to test the basic
operation of the unit. The unit also runs daily, weekly and monthly automatic Self-Tests when a
non-depleted 9V battery is present.
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.
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 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 done, the unit will announce its status and power off.
If the Self-Test passes: The unit will announce “UNIT OK” .The unit may then be immediately used
by pressing the ON/OFF button again.
If the Self-Test fails: The user should refer to the “Troubleshooting” section in Chapter 5 of this manual.
5.2.4 Replacing Pads
The Defibtech defibrillation/monitoring pads are intended for one time use only.
The pads must be replaced after each use or if the package has been damaged.
The DDU-100 AED defibrillation/monitoring pads are supplied in a sealed
pouch with the connector and part of the cable exposed. The DDU-100 AED
is designed to be stored with the electrode cable already installed. This allows
the pads to be stored in a pre-connected state for rapid deployment during an
emergency.
Caution: DO NOT remove the defibrillation pads from the sealed package until
the pads are to be used. The packaging should be opened only immediately
prior to use, otherwise the pads may dry out and become non-functional.
First, check to ensure that the pad package has not expired. Pads past their expiration date
should not be used and should be discarded. Next, check to ensure that the pads package has
not been torn, opened or damaged. Dispose of the pads if the package is open or damaged.
Inspect the pads cable and replace if any nicks, cuts, or broken cables are found. Insert the
connector end of the defibrillation pad cable into the pads connector port on the corner of the
AED as shown. Press the pads connector in firmly until it is fully seated in the unit.
