Hello.

What kind of problem is occurring when LM5 is flashing red? 
As you can see in the video, the red LED is flashing.

I discovered this issue when inspecting various facilities for safety after a large earthquake.

Please tell me the cause of this and how to solve it.

best regards,

This is normal operation. You can see the internal heartbeat status LED because it's dark.

Thank you for replying to me.

Really?

I have a test environment for LM at my workplace, so I have the opportunity to see it in an activated state on a daily basis, but I have never seen it.
As I mentioned the other day, the first and last time I saw the LED at the bottom flashing was when I was inspecting the equipment after the earthquake.

I have 5 LMs next to me and they all blink RED inside.
