How do you use a Budapest 5/30 travelcard?

When looking over the WikiVoyage Budapest page of public transport tickets, I spotted an interesting looking ticket for a trip which sees me needing to travel quite a bit on two weekends, but not the week inbetween:

5/30 travel card: 5 one-day travel cards. This booklet of 5 slips is valid for 30 days. Before beginning a 24 hour period of travel, mark the date and time with pen on an unused slip. Do not tear even used slips out of the booklet.

I also found something about it on the English BKK website, but I'm not sure I've fully understood it. Given the warnings on the WikiVoyage page about ticket inspectors showing no lenience to confused tourists, I don't want to get it wrong!

Assuming I can find somewhere to sell me one of these on arrival:

Am I correct in thinking it offers unlimited use of trams, buses and metros, with unlimited transfers, for 24 hours after each ticket starts?
What must I (and mustn't I) write and where whenever I want to start a new 24 hours?
Do I need to do any validating of the ticket when using it, or is writing in enough?
