 2.4  Establishing the Network Connection

A wired LAN connection is required for the initial setup. 
This also applies to the WiFi capable WLAN models, as 
the wireless connection’s login data needs to be 
entered before WiFi can be used.
Therefore, please connect Querx to your network or 
directly to the computer you intend to use to configure 
the device, using a network cable.

 2.5  Power Supply

1.

Prepare the power adapter by inserting the plug that 
is used in your country. An audible click indicates that
the connection has been made.

Now connect Querx to the power adapter using a micro-
USB cable and plug the power supply into a socket. The 
Querx status-LED will now light up yellow.

Danger

Never use the device with a defective power adapter! 
Risk of death from electrical shock!

Querx can alternatively be connected to a free USB-
Port, if no free power outlet is available.
