Hello!

I guess there can be two possibilities, either the device connection to the external supply (12-30V) is cutting off or your devices going to sleep mode. You can check the sleep mode parameters in System settings.

Thanks & Regards

Hi,

I have the same problem. Our FMB920's are shutting down after about 30-60 min, they are connected to a 9V battery with 800mAh. Ignition and movement source are configured on Accelerometer. When I disconnect and connect them again, they are working again and I can see that the internal battery has enough power (60%). These trackers are working 3hours a day only and configured on Deep Sleep after a timeout of 15min.

Do they need a minimal 12V power supply to operate stable?

Hello

Please provide screens from the system and status tab from the Configurator.

What is power voltage level ?

What do you mean by no longer turns on ?

Is internal battery connected, if yes please disconnect it and try to power up device.
