If you do not have a network connection at the place where your Snom phone is used, e.g. at trade fairs, information booths or a gatehouse, you can also integrate your device into your telephone system via a WLAN connection. You need only a WLAN USB Stick attached to the Snom Deskphone at booting time.
Since in this case there is no PoE power supply available, you have to electrify your Snom phone with an Accu or power supply (5V).
Use the arrow keys to navigate to the menu item: WLAN.
Select your desired WLAN hotspot and enter your password.
