To update a unit status when it is not on a call, which command should be used?

The correct command to update a unit status when it is not on a call is typically structured in a specific way. The command that indicates a unit’s status without being on a call often includes a designation, such as “PS,” which stands for "patrol status."

In this context, the choice that provides the clear and concise format required for updating the unit status effectively meets the necessary criteria. It signifies that the unit is in a particular status while not being actively engaged in a call or emergency response.

Other options may lack the structured format or specific indications that designate a unit's activity status clearly. For example, the first option seems to use a different format suggesting a specific command that may not directly relate to the update of status, which can be more appropriate for other contexts. The remaining options also indicate a unit status but may not conform to the precise command structure or clarity needed for a swift update in situations where communication efficiency is critical.

Thus, the correct choice effectively communicates the unit’s status in alignment with the standardized operational protocols utilized by the Nevada Highway Patrol.
