not unique to the software release.
Important: After pressing the information icon, review the full software version le name. In the middle of this
long le name you see the V152 (numerically lower if the radio is not up to date, or numerically higher if newer
versions were released and installed).
Inspect the current radio software version. Navigate to Settings -> About -> Build Number -> Information icon
view and verify the software version.
