6 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.

6.1 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.

Daily Monthly After Each Use Action

• • • Check that the Active Status Indicator (ASI) is ﬂashing green

• • Check the condition of the unit and accessories

• Run manually-initiated self-test

• Replace pads

• Check pad and battery pack expiration dates

• Check the DDC card, if one was installed

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 ﬂash 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 ﬂashing red, solid red, or not ﬂashing at all, the AED needs service. Anytime the ASI is ﬂashing

red, the unit will periodically emit two “beeps” to call attention to it.

If the ASI is not ﬂashing 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 ﬂash green. If it still does not ﬂash green after inserting

a new battery pack, the DDU-2000 Series AED is non-operational and may need servicing. Call Deﬁbtech for service.

(Refer to the “Contacts” section in Chapter 13 of this manual.)

If the ASI is ﬂashing 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.
