SCSO Detention Practice Test

What does the 10-21 code indicate?

In service, available Repeat Call by telephone Disregard

Correct Answer:

Call by telephone

Explanation:

Ten-codes speed up radio traffic, and a request to call by telephone signals that the conversation should take place over a phone line rather than over the air. This is used when the information to be exchanged is lengthy, sensitive, or better kept private, or when radio channel space needs to be kept clear for urgent matters. The dispatcher will arrange a phone contact with the officer or the person they need to reach, often using a provided number. This is different from being in service and available, which means you’re ready to respond; or from asking to repeat a message, or from disregarding a prior instruction.
