What chime do you hear when the flight deck calls for a non-emergency on the CRJ 200?

When the flight deck calls for a non-emergency, the CRJ 200 uses a one HI/LO chime. This distinct chime is part of the aircraft's communication system designed to alert the cabin crew of specific situations without indicating urgency. The HI/LO chime signals an instruction or a communication that requires the attention of the flight attendants but does not pertain to an emergency scenario. This helps ensure that the cabin crew can distinguish between different types of calls and respond appropriately based on the nature of the communication from the flight deck. Understanding this chime is essential for flight attendants as it directly affects their response protocols in various operational situations.
