Establishing a radio connection with a WiMAX network
The Basic Setup Wizard will now scan the frequencies to establish an initial radio con-
nection to a WiMAX network.
The frequency scan begins automatically. A progress bar indicates how far the scan
has progressed. In addition, you will see in the
Remaining time area roughly how
much time is still needed for the complete scan. Depending on how your SE680 WiMAX
modem has been preconfigured by your provider, the scan can last several minutes
before the first radio connection is established.
As soon as a radio connection has been established with a WiMAX network, the scan
will end. The progress bar is fully filled in and the display in the
Remaining time area
jumps to 0 seconds .

If the scan has been successful, read on in Chapter "Precisely aligning the antenna"
on page 22.
If the scan has not been successful:
The integrated antenna is a directional antenna this means that it must at least be point-
ing roughly in the direction of a WiMAX network base station in order to establish a
radio connection. The access data must also have been entered correctly.
If the scan was not successful:

First check your access data by going back to the WiMAX configuration page
(

page 20).

If you have entered your access data correctly, adjust the SE680 WiMAX modem.

Turn your SE680 WiMAX modem by approx. 20°. Turn or move the device a little at
a time and note the signal strength display. Use this to move the antenna to the
position with the best signal strength.
i
During the scan, the SE680 WiMAX modem must not be moved; this is
the only way to guarantee a complete scan with the current antenna
alignment.
