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-100 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.
