What action should be taken after a PJM All Call if you want to repeat the message?

After a PJM All Call, pressing "1" is the designated action to repeat the message. This function ensures that all participants can clearly understand the important information conveyed during the call. Repeating the message is crucial since it allows individuals who may have missed any details during the initial announcement to catch up without needing a separate call.

The ability to repeat a message is particularly important in high-stakes environments like PJM's operations, where accurate and timely information is essential for decision-making. Recognizing the appropriate command can improve communication efficiency and enhance the overall responsiveness of the team.
