When should a radio check be performed?

• A. At incidents and when establishing a new channel or crew
• B. Only during drills
• C. Only after shift changes
• D. Only when batteries are new

Answer: (A)

Radio checks ensure you can hear and be heard on the assigned channel when you actually need to operate. They’re most crucial at incidents and whenever a new channel or crew is established. At an incident, factors like distance, terrain, interference, and the number of users can affect signal quality, so a check confirms the link is reliable before you rely on it for coordination and safety. When a new channel or crew is set up, configurations can change, and you may be using different equipment or talk groups; testing verifies that the correct channel is active, communications are clear, the battery is charged, and the mic and earpiece work. Drills are useful for practice, but the immediate, real-world reliability is best ensured at the start of an incident or whenever a new channel/crew comes on line. Battery status should be checked as part of the process, not only when batteries are new.
