Additional information:
The z21start can only be unlocked using a WLAN or LAN-compatible Windows notebook/PC.
The activation code can also be generated using a second Internet compatible device (notebook, PC, Smartphone,
tablet). This makes it possible to keep the PC connected to the Z21 between steps 2 and 5, thereby making the normal
network switching unnecessary.
Caution:
The Z21 network is not to be connected to an existing home network when in the delivered state as this triggers an
address conflict, resulting in a temporary deactivation of both of the networks. Basically speaking, the connecting of a
Z21 network to a home network is possible but the Z21 router is not preconfigured for this as standard. Such a con-
figuration makes a certain network knowledge necessary. Please feel free to contact our hotline should you have any
questions.
