• Battery-installation self-test
• Power-on self-test
• Manual self-test
• Automatic self-test configured for either 1-day or 7-day intervals
• Automatic monthly self-test

The self-tests evaluate:

• Battery capacity
• Pad connection and expiration
• Battery expiration
• ECG circuitry
• Defibrillator charge and discharge circuitry
• Microprocessor hardware and software
• CPR circuitry and sensor when compatible pads are connected
• Audio circuitry

The battery-installation, manual, and automatic monthly self-tests include a 200-joule charge and discharge test. Other self-tests include a 2-joule charge and discharge test.

The manual also lists:

• A periodic physical inspection
• Cleaning after each use
• An optional maintenance test for technical professionals using a ZOLL AED Simulator

The manual does not specify a fixed annual, semiannual, or other calendar interval for the physical inspection or optional simulator test. Facility policy should establish the scheduled PM interval while preserving the manufacturer-listed self-test configuration and inspection activities.

5. Inspect the Defibrillation Pads

Verify:

• Pads are compatible with the AED 3
• Pad cable is connected
• Package is sealed
• Package is not torn, punctured, crushed, wet, or previously opened
• Pads are within the expiration date
• Correct adult or pediatric pads are available according to the facility configuration

Replace expired, opened, damaged, used, or incompatible pads.

Expected outcome: Compatible, sealed, unexpired pads are connected and ready for use.

6. Inspect the Battery

Verify:

• Battery is properly installed
• Battery is within its install-by or expiration date
• Battery compartment and contacts are clean and undamaged
• There is no swelling, cracking, leakage, or other physical damage
• No repeated CHANGE BATTERY message has been reported

The manufacturer does not list a fixed battery-replacement interval in this manual. Replace the battery based on expiration, low-battery indication, self-test failure, damage, or failure to support normal AED operation.

Expected outcome: Battery is installed, undamaged, within date, and not indicating replacement.

7. Check the Standby Readiness Indicator

With the AED powered off, verify that the status indicator displays a green check.

A blank indicator means the AED failed its last self-test or is not ready for use.

Expected outcome: Green check is displayed.

If the indicator is blank:

• Verify the pad connection
• Check or replace the pads as indicated
• Check or replace the battery as indicated
• Perform a manual self-test

Remove the AED from service if the green check does not return.

8. Perform the Manual Self-Test

Press and hold the On/Off button for at least 5 seconds.

Allow the AED to complete the manual self-test.

Verify:

• The test completes without failure
• The AED does not issue UNIT FAILED
• No unresolved battery or pad message is displayed
• The status indicator returns to a green check

The manual self-test includes the manufacturer-listed self-test functions and a 200-joule charge and discharge test.

Expected outcome: Manual self-test passes and the green check is displayed.

9. Verify Power-On Operation
