If you observe radio interference or equipment malfunction during a 900 code, what steps should you take?

• A. Switch to an alternate channel, inform dispatch, and document the issue for maintenance.
• B. Ignore it and continue transmitting.
• C. Immediately stop all operations and wait for maintenance.
• D. Record the issue after the incident ends.

Answer: (A)

Promptly addressing radio interference or equipment malfunction is essential for maintaining reliable communications and crew safety. When you notice interference on the 900 system, the immediate step is to switch to an alternate channel. This keeps ongoing operations from being disrupted by garbled or missed messages on the affected channel and helps preserve command and coordination.

Next, inform dispatch right away. They need to know what you’re experiencing so they can adjust traffic, potentially switch units to a clear channel, and log the issue for follow-up. Clear, timely communication with dispatch keeps everyone aligned and prevents miscommunication during critical moments.

Finally, document the issue for maintenance. Note the time, channel, a brief description of what you observed (noise, static, loss of clarity, equipment symptoms), any devices involved, and any actions you attempted. This creates a record that maintenance and IT can use to diagnose and fix the problem, reducing the chance of recurrence and preserving future readiness.

Ignoring the problem, stopping operations completely, or delaying reporting until after the incident ends can endanger safety and degrade mission effectiveness, which is why those options aren’t appropriate.
