Therefore, if a user was transmitting a multi-select call on talkgroup 1808, the

scanner would actually receive those transmissions on 1815. Some common uses of

these status bits are as follows:

• When a user hits their emergency button, all conversations on the talkgroup

revert to the emergency status talkgroup (ID+2) until the dispatch clears the

emergency status. Therefore, if someone hit their emergency button and their

radio was on talkgroup 16, all communications would switch to talkgroup 18.

• A lot of Fire and EMS departments dispatch tone-outs and alarms as Multi-

select communications (ID+7). Therefore, if your re department dispatch

talkgroup is 1616, and they do dispatch tone-outs and alarms as Multi-

selects, then those communications will be on talkgroup 1623.
