Maintenance and Troubleshooting

This chapter describes the maintenance and troubleshooting procedures for the DDU-2000 Series AED. The self-
tests that are automatically performed by the device are described along with recommended routine maintenance. A
troubleshooting guide is provided to help diagnose user serviceable problems.
The DDU-2000 Series AED contains no user serviceable parts.

5.1 Routine Unit Maintenance

The DDU-2000 Series AED is designed to be very low maintenance. Simple maintenance tasks are recommended
to be performed regularly to ensure its readiness (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.

Note: If the unit has been dropped, mishandled, or abused, a manually initiated self-test should be performed.
Checking The Active Status Indicator
The Active Status Indicator (ASI) is located to the right of the ON/OFF button of the DDU-2000 Series AED and
indicates the operational readiness state of the unit. The ASI will periodically fl ash green to indicate that the unit is
ready for use. Ready for use means that the DDU-2000 Series has passed the most recent self test (scheduled or
user initiated). If it is fl ashing red, solid red, or not fl ashing at all, the AED needs service. Anytime the ASI is fl ashing
red, the unit will periodically emit two "beeps" to call attention to it.
If the ASI is not fl ashing at all, the most likely cause is that the battery pack needs to be replaced. (Refer to the
"Installing And Removing The Battery Pack" section in Chapter 3 of this manual.) Once the battery pack has been
replaced with a fresh battery pack, the ASI should once again fl ash green. If it still does not fl ash green after inserting
a new battery pack, the DDU-2000 Series AED is non-operational and may need servicing. Call Defi btech for service.
(Refer to the "Contacts" section in Chapter 13 of this manual.)
If the ASI is fl ashing red, turn the DDU-2000 Series AED on. If the unit does not turn on or does not speak, the AED
is non-operational and requires servicing. If the unit does turn on, then turn the unit off and the voice prompts will
indicate the nature of the problem.
