To remove the DDC card, press the DDC in all the way and then release. The DDC will be partially
ejected and can be removed by pulling it the rest of the way out. To install a new DDC, insert the
DDC, label side up, in the thin slot on the top of the opening for the battery pack. 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.
Note: A DDC is not required for the DDU-120 AED to operate. Even if a DDC card is not
installed, basic essential information will still be recorded internally. The AED will still operate
properly even after a “replace memory card” message.
5.3 Replacing the Lithium 9V ASI Battery
The 9V ASI battery is located in the battery pack in the 9V
battery compartment (see figure). To install, remove the cover
covering the 9V battery compartment by pushing on it sideways.
The cover will slide approximately a 1/4 inch and then can be
detached 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 reversing the process used to remove the door.
If the battery pack is stored out of the AED for an extended period of time, removal of the 9V
battery will extend the 9V battery’s life. Note that in an emergency situation, the battery pack may
be used without a 9V battery. If needed, a non-lithium based 9V battery may also be used, but
standby status indication life will be reduced.
Once the fresh 9V battery is installed, the battery pack status LED should periodically flash green
to indicate a ready state. If the indicator does not flash, either the battery pack is defective or
the 9V battery is discharged. Once the battery pack is installed into the unit, the DDU-120 AED’s
status indicator should periodically flash green.
Note: The unit will operate without a 9V battery installed, but active status indication and
automatic self-tests will not be provided. Status can still be checked by turning the unit on.
