What is the primary information that needs to be documented in the remarks when a call is transferred to the low priority announcement?

The primary information that needs to be documented in the remarks when a call is transferred to the low priority announcement is the "LPT played." This refers to the specific Low Priority Tone (LPT) that was signaled, indicating that the call is being classified in a low-priority status. This documentation is crucial because it provides clarity regarding the handling of the call and ensures that subsequent officers and dispatch personnel can effectively track how the situation was managed. Monitoring low-priority calls is essential for resource allocation and ensuring that they are addressed in a timely manner without undermining the response to higher-priority incidents.

The other options do not capture the specific procedural element that is essential for transferring the call to low priority status, which is why they are not the primary focus in this documentation.
