It is vital that an AED is kept in tip-top condition so that will work when it is needed. The AED is a clever device which checks itself every minute and flashes its external green “I am OK” light. AED owners are encouraged to take a look at the AED every day and check for the green light.
Once a year each AED must be serviced by a skilled technician who:
- checks out the software, applying upgrades when required,
- checks out the main “shock” battery to ensure it is fully powered and able to deliver a shock when needed,
- replaces electrode contact pads if they are expired
- replaces the small battery which powers the continuous self-diagnosis and the voice commands
