Cycling through the Units Buttons?

[Geraldb13]

Quick newbie question. Can anyone quickly tell me the difference between the "Next Unit" button and the "Leave Unit & Get Next one" button directly below it. The CD manual was a bit confusing , especially when describing the effect of the "Leave Unit & Get Next one" button. Thanks!

Cycle through units does just that.. it will cycle through the units.. leave and forget button flags that unit as no longer being part of the cycle through units cycle - if you know what I mean.

If you leave and forget each unit you will eventually end up with no more units which can cycled.. where as with just cycle through units you will continue to cycle through them and start repeating the cycle.

Rob,
Thanks for the response. I understand now, but I'm curious about something...
Suppose I can cycle through 10 units and I've currently selected unit 1. If I click on the "Leave Unit & Get Next one", I assume I move off unit 1 to unit 2 and will cycle from 2 through 10 and back to 2. If I continue to hit the "Leave Unit & Get Next one" will I eventually get stuck on unit 10 only, and how do I restore the initial cycling capability? Or does this button simply set a flag and once I de-select it, I can't cycle back?
Anyway it's a trival point which I can test on my own. Thanks again.
