What is the protocol for radio checks when starting a shift?

• A. Skip radio checks until the end of the shift.
• B. Test the mic, verify channel, and confirm unit identifier with dispatch before operations.
• C. Only verify the channel, ignoring mic test.
• D. Verify channel after the first transmission and then proceed.

Answer: (B)

Before you begin moving on calls, you perform radio checks to confirm three things: the microphone works, you’re on the correct channel, and dispatch has your unit identifier. Testing the microphone ensures your voice is transmitted clearly so messages aren’t muffled or lost. Verifying the channel guarantees you’re on the right talk group or frequency, so you receive and send communications with the intended unit and team. Confirming your unit identifier with dispatch creates proper recognition and accountability, letting dispatch route responses accurately and log your activity.

Skipping these checks, or doing only part of them, risks being unheard, miscommunicated, or misidentified during active duties. Verifying the channel after the first transmission can cause delays and confusion, since you might already be communicating on the wrong channel or without proper identification. By performing all three checks at the start of the shift, you establish reliable, clear, and trackable communications from the outset.
