Correct, it runs on a 2 hour loop. If not turned off, it keeps running.
Interesting in Europe they run on 25 hour loops. Wonder why?
Because the Airline companies and Pilots did not want it running move than 2 hours so that there would be no record of “embarrassing” recording. In the age of digital recordings and hardware, seems to me 2 hours dates back to a time of TEAC recorders! Equally ironic, when we used body in my job in the 70s, we had recorders that ran for almost 4 hours, AIDS.

I was thinking it was 2 hours as well. So that sounds correct.(?)
