How does the defib reach the service location, how long will you be without it, and how does it return?

You will never be without a defib. When your defib is due for a 2-yearly maintenance service, we will visit you to collect your defib. At the same time, we will bring another defib for you, one that has just had a maintenance service and is 100% ready for use for the next 2 years. We leave this defib with you for the next 2 years.
