In terms of communication discipline, what should be avoided when a 900 code is in standby?

• A. Proactively sending all possible details to every unit.
• B. Leaving channel silent and not updating.
• C. Referring to other incidents in standby messages.
• D. Including the reason for standby, expected time, and next update.

Answer: (D)

When a unit is in standby, the focus is on keeping the channel clear and avoiding commitments or explanations that might become outdated. Including the reason for standby, the expected time, and the next update can create expectations and crowd the line with information that may change, leading to confusion or miscommunication. By avoiding those details, you maintain flexibility and prevent stale or conflicting information from circulating.

Other options clutter the channel, leave it unresponsive, or inject extraneous references, all of which undermine clear, efficient communication in a live situation. In standby, a minimal, non-committal status is preferred, with updates only when there’s a meaningful change.
