Pressing sync and no beeps

I just purchased and received new eufycam e 2 camera packages. I connected the power and the ethernet cable. White led is blinking on homebase.

I can not add the homebase…whathever I do. Im always stuck where I should press the sync button on the base. I can press it for 2 or 30 second…no beeps.

Can someone help me? Thx
