During a high-threat incident, operators are instructed to refrain from transmitting on the radio for a period.

• A. Non-Police Help Call
• B. Switch Radio Channel
• C. Hold Radio Transmission
• D. Prowler

Answer: (C)

During a high-threat incident, keeping radio chatter to a minimum is crucial for stealth and coordination. Refraining from transmitting for a period—holding radio transmission—creates a temporary radio silence that prevents revealing positions, movements, or plans to anyone who might be listening, while letting critical operations happen with less interference on the channel. This discipline helps ensure responders can resume clear, organized communications later without warning or clutter.

The other options don’t fit this directive. Non-Police Help Call is about summoning assistance from non-police sources, which isn’t about radio behavior. Switching radio channels changes the frequency you’re on, not the act of preserving silence for a period. Prowler refers to a type of suspect, not an action or instruction for radio use.
