A Group Scan is an optimized way to scan for multiple groups on the same channel (slot). The radio monitors the channel from either the repeater or directly from another radio to determine which group is currently transmitting. If the group transmitting is one specified in the Group Scan List, the radio will stop and listen. The radio is allowed to talkback to the group for the duration of the call hang time. This call hang time overrides the TX Contact Name setting of the channel. Because only one call takes place on a channel (slot) at any given time, the scanning radio will not miss a transmission of interest, regardless of the length of the group list. A Group Scan is configured by creating a group list and adding groups already in the Contacts folder. This group list can then be selected as the RX Group List of a particular Channel. The Group Scan does not have the advanced features and configuration options of a channel scan. For example, once configured via CPS, the Group Scan cannot be turned on or off and members cannot be added or removed. Furthermore, the configurable scan options (Scan Hang time Timer, Talkback, and others) do not control the Group Scan. The Group Scan should be used in simple systems where no advanced scan options are required. If advanced scan options and features are required, a Channel Scan should be configured instead.
