I have heard that you must upgrade in steps if you are moving up beyond the next revision in order to retain programming. If you are moving from 4.x to 6.1, I would recommend doing a system startup to re- intitalize with the new S/W to avoid any corruption and glitches. I like to start with a clean slate. I don't know if it's really necessary, though. Better safe than sorry...


Also......GET THE MICS XC 6.1 MR!!!!
The MR is a maintainance release that will save your ass 10 months down the road when the system locks up channels.

I replaced 3 6.1XC's this year with MR.

GET IT!


Punch down all your damn pairs!..........(please).
