In a CAD environment, the message "status 8" may be translated by the CAD system to a meaning such as "available". "Status 1" might mean "starting a meal break". Key caps on the radio's status buttons may be engraved with their user-defined status. The unit's status changes at the moment the button press is received. This helps take a load off the dispatcher because the status change is logged automatically. This happens even though the dispatcher may be talking on the telephone. In systems where the dispatcher is often overloaded, the use of status buttons may slightly reduce the work load and may reduce voice message traffic on a channel.
