7.2 Self-Tests
The DDU-2000 Series AED provides for both automatic and manually initiated self-tests. These self-tests test
various components of the AED, including the system controls, battery pack condition, charge/discharge functions,
and measurement and signal acquisition functions.
Automatic Unit Self-Tests
Every time the unit is turned on, power-on self-tests are performed to test the basic operation of the unit.
The unit also performs daily, weekly, monthly, and quarterly self-tests automatically (without any intervention from
the operator) to check the integrity of the unit’s hardware and software. The unit will also perform a battery insert
self-test when the battery pack is inserted.
Manual Self-Tests
Manually initiated self-tests may be run at any time by the user to test the DDU-2000 Series AED’s systems, including
the charging and shocking functions (the shock is internally dissipated; i.e., no voltage will be present at the pads).
To run a manually initiated AED test, the unit must be put into Maintenance Mode. (Refer to the “ AED Maintenance
Screen ” section in Chapter 8 of this manual for detailed information on performing these self-tests.)
Note: Running a manually initiated self-test will consume approximately one shock’s worth of energy from the battery.
7.3 Cleaning
After each use, clean the DDU-2000 Series AED of any dirt or contaminants on the case and connector socket.
The following are important guidelines to be adhered to when cleaning the device: (Also applies to ECG Monitoring

• The battery pack should be installed when cleaning the DDU-2000 Series AED.
• Do not immerse the DDU-2000 Series AED in fluids or allow fluids to enter the unit.
• Do not spray cleaning solutions directly on the unit or its connectors.
• Do not use abrasive materials or strong solvents such as acetone or acetone based cleaning agents.
• To wipe the DDU-2000 Series AED's case clean, use a soft cloth dampened with one of the following recommended
cleaning agents:
– Soapy water
– Ammonia based cleaners
– Hydrogen peroxide
– Isopropyl alcohol (70 percent solution)
– Chlorine bleach (30 ml/liter water)
• Ensure that the connector socket is completely dry before reinstalling the pads cable. After cleaning, allow
the unit to completely dry. Before returning it to service, always check the AED operational status. (Refer to
“
Checking The AED Status Using The AED Status Screen ” earlier in this chapter.)
7.4 Storage
The DDU-2000 Series AED should be placed in a readily accessible location in an orientation where the Active Status
Indicator (ASI) next to the ON/OFF button can be easily seen. In general, the unit should be stored in clean, dry and
moderate temperature conditions. Make sure that the environmental conditions of the storage location are within
the ranges detailed in the “
Environmental ” section in Chapter 11 of this manual.
