Found it. However, when I modify this time (even from 0 to 10, or any other value), it has no affect. As a test I loaded the favorites with 4 different P25 systems and changed them all to 0, then 10. At this point I'm not sure what's going on. BTW, any time I reload from the computer, the value in this time defaults to 0 on my scanner. Using Proscan and Sentinel.Then you are looking at the wrong timer. It is under the Manage Favorites/'system name'/Review-Edit System/'system name'/Edit Sys Option/Set Hold Time.
