What does 10-97 stand for in law enforcement communication?

In law enforcement communication, the code 10-97 signifies that an officer is "Onscene." This code is utilized to inform dispatch and fellow officers that they have arrived at the location of an incident or are present at a particular scene. This designation is critical for maintaining situational awareness and coordinating response efforts among various units. When an officer communicates their status as "Onscene," it enables other responders to know they can proceed with their operations, making it a key part of effective communication in field operations.

The other options refer to different statuses or actions not conveyed by 10-97. For instance, the code for backup or needing additional assistance would be different, just as the completion of an assignment and radio channel changes utilize their respective codes to ensure clarity and efficiency in communication.
