Question 1 of 27070

The determining factor of the setting of the sensitivity control of an auto-alarm receiver:

🔍 Key Concepts

• How an auto-alarm receiver is supposed to respond to distress signals • Difference between unwanted noise/interference versus the desired distress signal • What the sensitivity control actually adjusts inside a radio receiver

💭 Think About

• Ask yourself: What is the main purpose of the auto-alarm receiver, and what must it reliably detect every time? • Which factor should the operator use as a reference when setting sensitivity: changing noise conditions or the level of the signal that must be received? • If you set sensitivity based mainly on static/interference, what risk does that create for receiving a weak but valid distress signal?

✅ Before You Answer

• Identify which choice refers to the desired signal rather than background conditions • Consider which factor is constant for proper operation versus which ones vary moment to moment • Verify which factor would ensure that a weak but valid distress call will still trigger the alarm, without too many false alarms
