1 Introduction to the DDU-120 Series AED
This User Manual provides information to guide trained operators in the use and maintenance of the
Defibtech DDU-120 series Fully Automatic External Defibrillator (“AED”) and its accessories. This
chapter includes an overview of the AED, a discussion of when it should and should not be used, and
information on required operator training.
1.1 Overview
The DDU-120 AED is a Fully Automatic External Defibrillator (“AED”) that is designed to be easy
to use, portable and battery powered. It has only one user control: the ON/OFF button. Voice
prompts and visual indicators provide a simple interface for the operator. The DDU-120 AED is
capable of recording event information including ECG, audio data (optional), and SHOCK/NO-SHOCK
recommendations.
When connected to a patient who is unconscious and not breathing, the DDU-120 AED performs the
following tasks:
• Prompts the operator to take necessary actions to enable analysis.
• Automatically analyzes the patient’s ECG.
• Determines whether a shockable rhythm is present.
• Charges the defibrillation capacitor.
• Automatically (without user intervention) delivers a shock once the device has determined a
shock is required.
• Prompts the user to administer CPR if needed.
The DDU-120 AED will shock the patient automatically, without additional interaction by the user, if a
shock is required.
The DDU-120 AED uses two self-adhesive defibrillation/monitoring pads to monitor ECG signals and,
if necessary, to deliver defibrillation energy to the patient. These pads (also known as electrodes) are
provided in a single-use, disposable package.
The DDU-120 AED determines proper pad-to-patient contact by monitoring the impedance between
the two pads (impedance varies with the electrical resistance of the patient’s body). Visual and audio
prompts inform the operator of possible problems with patient contact. Voice prompts and visual
indicators communicate the status of the AED and of the patient to the operator. The DDU-120 AED
has one push-button control and several LED indicators.

2
DAC-530E-EN-BH
Defibrillation energy is delivered as an impedance compensated biphasic truncated exponential
waveform. The device delivers 150 Joules into a 50-ohm load when using adult pads or when
using attenuated child / infant pads, 50J of defibrillation energy into a 50-ohm load. Energy
delivered does not change significantly with patient impedance, although the duration of the
generated waveform will vary. The Defibtech AED is designed to deliver up to 150J of defibrillation
energy through a patient impedance range of 25 – 180 ohms or 50J of defibrillation energy when
using the child / infant pads.
Defibrillation and AED operating power is supplied by a replaceable (non-rechargeable) lithium
battery pack that provides for long standby life and low maintenance operation. Battery packs are
available in several configurations optimized for use in specific applications. Each pack is marked
with an expiration date.
The DDU-120 AED records event documentation internally and, optionally, on Defibtech Data Cards
(“DDC”). The optional DDC plugs into a slot in the AED and enables the AED to record event
documentation, and audio (audio enabled cards only) if sufficient space is available on the card.
Audio recording is available only for units with installed audio-enabled Defibtech Data Cards. Event
documentation stored internally can be downloaded onto a DDC for review.
1.2 The Defibtech DDU-120 AED
A. Speaker. The speaker projects the voice prompts when the DDU-120 AED is on. The
speaker also emits a “beep” when the unit is in standby mode and has detected a condition
that requires operator attention.
B. SHOCK required indicator. This indicator will flash when a shock is recommended and the
unit has charged and is to deliver a shock. Do not touch the patient while this indicator
is flashing.
C. “analyzing” LED (Light Emitting Diode). This green LED flashes when the DDU-120 AED is
analyzing the patient’s ECG rhythm.
D. “do not touch patient” LED. This red LED flashes when the DDU-120 AED detects motion
or other interference that prevents analysis of the signal or when the user should not be
touching or moving the patient.
E. “check pads” LED. This red LED flashes when the DDU-120 AED detects that the pad
connection to the patient is poor or pads are not applied.
F. ON/OFF button. Push button to turn the DDU-120 AED on. Push again to disarm and turn
the AED off.
G. Pads connector port. Insert Patient Pads Connector (item O) into this port to connect pads
to DDU-120 AED.

H. Battery pack. The battery pack provides a replaceable main power source for the DDU-120 AED.
I. Battery pack opening. Insert the battery pack firmly into this opening until the latch clicks into
place.
J. Battery pack eject button. This button releases the battery pack from the DDU-120 AED. To remove
the battery pack, push the button until the battery pack is partially ejected from the unit.
K. Active Status Indicator (ASI). When the unit is off, this indicator blinks green to indicate the unit is
fully operational and blinks red to indicate unit needs attention from the user or servicing.
L. Patient pads. The defibrillation/monitoring pads that are placed on the patient. The pads may be
stored in the pad storage area on the back of the unit.
M. Defibtech Data Card (DDC). This optional plug-in card provides enhanced storage capabilities to
the DDU-120 AED.
N. Active Status Indicator (ASI) battery. This is a 9V lithium battery that provides power to the
Active Status Indicator. It is inserted into a compartment in the battery pack.
O. Patient pads connector. Insert into Pads Connector Port (item G) to connect pads to the DDU-
120 AED.

DAC-530E-EN-BH
3.2 Installing the Data Card
The Defibtech Data Card (“DDC”) is used to store event and audio
information collected by the AED. All DDU-120 AEDs will operate
without DDCs and will still store critical event information internally.
Different DDC versions store different amounts of information. DDCs
are available in versions that store and don’t store audio information.
Refer to the DDC technical specification for exact storage capabilities.
DDCs may be reviewed with a separate PC based software package -
see “Event Viewing” section.
To install the DDC, remove the battery pack and push the DDC, label side up, into the thin slot in
the side of the AED centered over the battery pack opening. The card should click into place and
be flush with the surface of the slot. If the card does not push in all the way, it may have been
inserted upside down. In that case, remove the card, flip it over and try inserting it again.
To remove the DDC, press the card in all the way and then let go. The DDC will be partially ejected
and can be removed by pulling it the rest of the way out.
3.3 Installing the Active Status Indicator 9V Battery
A user-replaceable lithium 9V battery, located inside the battery pack, provides Active Status
Indicator (“ASI”) power. This auxiliary battery is used to provide standby indicator power
independently of the main lithium battery (contained in the battery pack) allowing the main battery
pack to have a significantly longer shelf and standby life.
The unit will operate without a 9V battery installed in the battery pack, but active status indication
will not be provided. If no 9V battery is installed, status can still be checked by turning the unit
on. Only a fresh 9V lithium battery should be used as a replacement. Refer to the Maintenance
section for more information on replacement batteries.
The 9V battery is installed into the battery pack in the 9V battery
compartment. To install, remove the cover covering the 9V
battery compartment by pushing on it sideways. The cover will
slide and detach from the battery pack. Insert the 9V battery
into the 9V battery compartment so that the contacts on the
battery touch the contacts in the battery pack. The orientation of
the battery contacts is shown in a picture on the inside bottom
of the 9V battery compartment. Replace the 9V battery
compartment door by placing it in the almost closed position and
then sliding it closed.
