The R&S TSMX-PPS2 is being shipped with a factory configuration and is ready to
use. By means of the u-center demo application or by any customer application, it is
possible that these default settings are being re-configured in a way that the GPS
receiver won’t work properly anymore.
In order to overcome this, the device factory settings are part of the accessory CD-
ROM. This could be reloaded into the device by means of the u-center application (see
section
"Recover GPS Factory Settings"
on page 37).
