Go to Freescan, click on the names of the systems you have programmed, and check each one as follows:
Under the System Name, make sure Lock Out isn't checked. If it is, click on the check mark to remove it.
If that's okay, make sure you assigned each group a Quick Key number. After that, go to the bottom of the page where it says Enable/Disable Groups. If all of the boxes next to the numbers are blank, none of your groups are enabled and therefore, there is nothing to scan. You must have at least one group enabled in order for the scanner to have something to scan. To enable a group number, click on the appropriate box to put a check mark in it. And, of course, you would want to enable all groups you want to listen to.
If you need further help or explanation. post and we'll try to help you out.
