current location. If you have a lot of data programmed, it might take the scanner a couple of minutes to complete the process. Once the scanner completes the initial GPS review, if you move into or out of an area covered by a radio site, the scanner beeps and displays the name of the system and whether it is being locked or unlocked.
Note: The GPS function temporarily locks out sites and systems when you move out of their range. If you cycle power, all systems are unlocked until the scanner reacquires the GPS signal and completes the initial GPS review.
