It would also help to have you LMC activated with an account key (free by the way), that also will allow you to push radio features in the future.
I be my own rule offer a 5 seat set up so you can have 5 chances of being able to recover your software at the worst possible times.
That being said, there IS NO limit to the number of PC per account key. 1 to xxxx, but rule of thumb is for a single person, 5 is usually good.
NOTE: even with the LMC registered, radio features are a 1 time deal after 72 hours, that key belongs to that radio forever.
Some people will stress over there list having a key that says 0/1 and cant figure out how to pull it from the radio. Does not work that way.
Contact your local dealer or I can guide you on more information 1 on 1.
imow; does not hurt to get your LMC account key (jkefa) so you can move about pc's with your software.
*NOTE: WIDE BAND KEYS CAN NOT BE RECOVERED DUE TO ELECTRONIC FAILURES!
