Scan is a feature that allows a radio user to mon- itor activity on more than just his or her selected group. In general, a radio keeps a list of groups, or scan members, that it uses while in scan. The scan feature exists on different types of systems. For con- ventional systems, scanning means checking the he- quencies of scan list members for call activity in progress. For trunked systems, scanning means monitoring a control channel for channel grants. These grants are then compared against its scan list and ifa match is found, the radio moves to the voice channel to monitor the group's call.
