LOGO! CMR 2020 led keep blinking

Hi there, 

I am having problem to turn off the LOGO! CMR 2020. I have tried pressing the SET button for 5 - 10 seconds as mentioned in the manual. but the "L" led start to blink and it keeps blinking (according to the manual, all LED need to be off). 

Please advise.

Thank you.

The CMR wants to re-initialize or re-configure.

Edit:

Thanks for your reply. 

But how long will the led blink?

I have tried waiting for 10 minutes. 

Please advise.

Have you read the topic, whose link I posted?

More I can not wrote. Make a Support Request?

And then tell us the result....

Yes, 

I have read the topic.

Previously the sim card didn't have any pin, therefore i was not able to turn off the CMR.

After i set a pin, now i can turn off the CMR.

Thank you.

Hi there, 

I had inserted the same sim card that i was using yesterday back into the CMR again but this time before inserting the sim, i have removed the sim card pin. where then i click on the Apply button at the WAN page after leaving the sim pin field empty, and then the LED "L" starts to blink non-stop. I am not able to turn off the CMR via the webserver page. 

Please advise.

Thank you in advance.

Hi there, 

I would like to share what i have discovered.

Sim pin is a must in order to proceed to configure the CMR.

Thank you.

I was trying to test based on the uploaded file.

But the moment i click apply after leaving the sim pin field blank the LED started to blink and it never stopped blinking.

I had to power off and set a pin for the sim before re-inserting the sim and turning ON.
