CS1000: Description of Ranf, Ran1, & Ran2 on Miran??? 1

[newbie95]

Hi All,

Can anyone describe me , the function of Ranf, Ran1, & Ran2 on Miran??
What are differences of Ranf and Ran1??
When Ran2 is activated, what's actually active, Ranf or Ran1 as a primary??
Should the synchronized time be activated, when using Ran2 (not local time on Miran)??
What should I set, when I activate Ran2??

Any helps would be appreciated..

Thank you
