What is the standard procedure when a 900 code transmission is non-responsive?

• A. Ignore the transmission and move on.
• B. Attempt a call back, use alternate channels if necessary, and log the attempt.
• C. Wait for the other unit to respond.
• D. Immediately escalate to a supervisor without attempting contact.

Answer: (B)

When a 900 code transmission is non-responsive, the aim is to quickly re-establish contact and keep a clear record. Start by attempting a call back to the unit to give them another chance to respond. If there’s still no answer, switch to alternate channels or communication methods to reach the unit, using redundancy to overcome potential interference, range limitations, or channel congestion. Finally, log the attempt with the time, channels used, and outcome so there’s an auditable record for accountability and follow-up. This approach ensures you don’t miss critical messages, don’t waste time waiting without action, and still preserves a clear trail of communications. Ignoring the transmission or escalating without attempting the recovery steps would undermine safety and reliability.
