Is the bottom sensor "clicking" sound normal?

[kaitlyn]

I had my mavic sitting on my counter here and jsut turned it out to do some setup stuff and noticed that before the fans really started going, it was making a clicking sound. This was coming from the front downward sensor. If I "covered" it, then it muffled it which is how I determined it was only from that 1 sensor. Do the front and back downward ones perform different roles? Is this clicking sound to be expected? Nothing is being reported as malfunctioning

Ultra sonic is sound bounced down and then back up. So I'm guessing one sends a signal and the other receives it.

Correct. Perfectly normal sound.

Completely normal. One sends an US signal, the other receives the bounce back of it.

Correct. Perfectly normal sound.

I didn't have that sound before, but just now I turned on my mavic and heard the noise coming from one of the sensors? I'm kinda scared

Nothing to be worried about. It started when DJI updated the ultrasonic sensors.
