AC 300 new out of box it doesnt work

somebody at bluetthem help me please and yes i emailed

Assembled push power button on station
battery light comes on
the station light does not light
tried every combination of power cable from battery to station no power light comes on no screen lights up

Is AC input connected? Is there a B300 connected?

@landd You can check if you lock the cable entirely. If it is not work, you can disconnect AC300 and B300, and check if B300 can work separately. If B300 works, there is a problem with AC300.
