5.2 Routine Maintenance
The DDU-100 AED is designed to be very low maintenance. Simple maintenance tasks are
recommended to be performed regularly by the owner/operator to ensure its dependability (see
sample maintenance table below). Different maintenance intervals may be appropriate depending
on the environment where the AED is deployed, and ultimately the maintenance program is at the
discretion of the emergency response program’s medical director.
Daily Monthly After Each Use Action
• • • Check that Active Status Indicator (ASI) is flashing green
• • Check the condition of the unit and accessories
• Run manually initiated self-test
• Replace pads
• Check pads and battery pack expiration dates
• Check the DDC, if one was installed
Note: If the unit has been dropped, mishandled, or abused, a manually initiated self-test should
be performed.
5.2.1 Checking Active Status Indicator
The Active Status Indicator (“ASI”) is located in the upper corner of the DDU-100 AED and
indicates the operational readiness state of the unit. It will periodically flash green to indicate
a fully functional condition. If it is flashing red or not flashing at all, the AED needs attention.
Anytime the ASI is flashing red and a good 9V battery is installed, the unit will periodically emit a
“beep” to call attention to itself.
If the ASI is not flashing at all, the most likely cause is that the ASI 9V battery needs to be replaced.
Follow the directions in the “Replacing the Lithium 9V ASI Battery” section to replace the ASI
battery. Once the battery has been replaced with a fresh battery, the ASI should once again flash
green. If it does not, the battery pack may be defective. In that event, the battery pack should
be replaced. If it still does not flash after inserting a new battery pack, the DDU-100 AED is non-
operational and needs servicing.
