DAC-530E-EN-BH
The main battery is based on a lithium battery technology and provides the AED with a long shelf
and standby life. Battery pack status indication is provided by a blinking green status LED. Status
indicator power is supplied by a user replaceable 9V lithium battery.
6.2.1 Battery Pack Active Status Indicator
The battery pack’s Active Status Indicator (“ASI”) is located on the label
face of the battery pack and is used to indicate battery pack status. A
periodically blinking green LED indicates that the battery pack status is OK
and the battery pack is ready for use. Absence of a blinking green LED
indicates a battery pack problem or a depleted or missing 9V
battery. Refer to the “Checking DDU-120 AED Status” section for
information on battery pack LED indications.
6.2.2 Active Status Indicator Battery
The Active Status Indicator (“ASI”) battery is a 9V lithium battery. It
provides power to the Active Status Indicator to prevent the main
defibrillation battery from being depleted for non-essential functions.
This provides a significantly longer standby life for the AED and battery
pack and extends the lifetime during which the DDU-120 AED can deliver
defibrillation shocks. The Active Status Indicator battery is a lithium 9 volt
battery.
6.3 Data Cards
The DDU-120 AED is designed to optionally use Defibtech Data Cards
(“DDC”). The AED will operate with or without a DDC, but if a DDC is
installed, additional event storage capacity is available.
The DDU-120 AED accepts DDC cards of different capacities, each
designed to record an assortment of data for a given period of time. For
example, the DDU-120 AED can record more than ten hours of ECG only
or approximately one hour and forty minutes of audio and ECG data on
a large DDC card. Cards are available with and without audio logging
enabled.
