Hi Alberto,
Thanks for contacting Milesight-IoT Support Team,
Typically, the AT101 is shipped with 4 batteries already assembled inside the device by default. For first time use, you just need to turn on the device via Toolbox APP.
For more details about sensor configuration, please check: https://resource.milesight.com/milesight/iot/document/at101-user-guide-en.pdf
If you need to replace the batteries, just remove the hexagonal screws on the back of the device.
Any problems, feel free to let me know,
Have a great day.
Best Regards,
Mandarin Li
Thnak you very much
Best regards,
Alberto

Sorry for this basic question.
But I don´t know how to install the batteries into the AT -101 device?
Do you have some manual or video?
I could not find information about it.
It seems I have to remove the cover of the back, but I don´t see how.
