5 Maintaining and Troubleshooting the
DDU-100 AED
This chapter describes the maintenance and troubleshooting procedures for the DDU-100 AED.
The Self-Tests that are performed by the device are described along with the frequency and nature
of periodic maintenance for which the owner/operator is responsible. A troubleshooting guide is
provided to help diagnose user serviceable problems.
The DDU-100 AED contains no user serviceable parts except for the ASI 9V battery.
5.1 Self-Tests
Power-On Self-Tests are performed every time the unit is turned on to test the basic operation of the
unit. The unit also performs daily, weekly, monthly and quarterly self-tests automatically when a non-
depleted 9V battery is present to check the integrity of the unit’s hardware and software.
Manually initiated Self-Tests may be run to test the DDU-100 ’s systems, including the charging and
shocking functions (the shock is internally dissipated and no voltage will be present at the pads) at
any time.
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 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.
