received new IWork GT – screen stays black

Hello, I just received my iWork GT. After unboxing, tried to start it up, but the screen stays black. There is no manual inside the box (only ‘about the device / specifications’ page).

I connected the USB-C charger. A red LED lights up. When I press the start button , it changes to blue and after a few seconds back to red.

I once heard a femele voice giving me directions to press some keys. But I don’t have a keyboard yet.

Can someone help me out?

 

The usb interface of iwork gt can be connected to the usb keyboard and mouse for operation. If the machine has a prompt sound, you can confirm whether the machine is actually running, but the screen does not display
