#7530:30h

The #7530 is a hex number that sets the timer duration, which I fully understand. What is the ":30" at the end?

It means that its wordsize is 30 bits. Operations on it will be limited to 30 bits (try NOT on it) unless you specify otherwise. More info in Chapter 30 ("Basic integer arithmetic") in your HP Prime User Guide.
