Dispatches are done on channel 1.
When a unit becomes available, if updating status verbally, that is also on channel 1.
Once a unit is assigned to a call, they immediately switch all traffic to command channel (Channel 2 for brush fire, Channel 5 for calls in Camarillo, South Coast, Ventura, Fillmore, Santa Paula, Ojai, Channel 8 for Simi, Moorpark, and Thousand Oaks).
For on scene tactical channels, Units on Command 5 will switch to Tac 6, Units on Command 8 will switch to Tac 9, and Units on Channel 2 will switch to an assigned tac.
For most medical calls, there is very little Command channel traffic... as updates are sent via mobile data computer (MDC).
