What happens in the event of a power outage?
The important thing to remember is not to panic — the AirPod will automatically start to depressurise in the event of a power outage.
Once the pressure has decreased to 1.00, simply pull down on the edge of the door above your head, and this will release any final pressure remaining in the AirPod.
Once the door is safely open and in a secure position, please leave the AirPod.
In the event you would like to accelerate the depressurisation process, there is also a ‘red’ ‘Emergency Release Valve’ next to the internal control unit. This will provide a manual release of pressure that you control. "What happens in the event of a power outage?"
