In APCO 10-codes, 10-7 means "Out of Service."
This indicates that an officer or unit is no longer available for service or duty. It could be due to a shift ending, equipment failure, or another reason that takes the unit out of operation for a period of time. For example:
- Officer: "Dispatch, I'm 10-7 for the day."
It is used to inform dispatchers and other units that the officer or unit will not be responding to calls or available for assignments.
