Switching to Default Network Parameters – Static IP
Address
Switching to the default network parameters with the static IP address can be
performed in two ways. Either through a web interface as described in the Network
subsection or by pushing a combination of the quick dialling buttons as shown in
Figures 3.1–3.3. Upon resetting, the web server is automatically switched on if
switched-off before. The buttons have to be entered within 30 seconds after the
internal application launch as signalled by the tone sequence. The maximum
delay between the buttons is 2 s.
