A full list of frequently asked questions is available in the App “info” pages.
Error Remedy
No Wi-Fi
connection
The Wi-Fi signal from the Wi-Fi router is possibly not strong enough. Contact Wi-Fi provider, or
consider Wi-Fi repeater in some situations. Only compatible with “b” and “g” routers.
Wi-Fi network not found Hide function of the Wi-Fi-router is possibly switched on or broadcast function (transmitting the
SSID) is switched off. Temporarily switch the hide-function off or broadcast-function on.
This display
remains on
Wi-Fi network is possibly protected with “WEP64” protocol. This protocol is not supported.
Change the safety protocol of the router ( router manual).

manually allocate an IP-address in the router ( router manual).

back onto the wall plate. All Wi-Fi networks found are shown on the display ( section 4.6.3).
