7 Maintenance And Troubleshooting
This chapter describes the maintenance and troubleshooting procedures for the DDU-2000 Series AED. The self-tests
that are performed by the device are described along with the frequency and nature of routine maintenance for which
the owner/operator is responsible. A troubleshooting guide is provided to help diagnose user serviceable problems.
The DDU-2000 Series AED contains no user serviceable parts.
7.1 Routine Unit Maintenance
Although the DDU-2000 Series AED is designed to be very low maintenance, simple maintenance tasks must be
performed by the owner/operator on a regular basis to ensure the unit’s dependability.
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 14 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.
