lac, Display 01.14: Modify "last used band" (Version: 1, Status: Approved)
This display is applicable only in phones having both European and American frequencies.
With this display it is possible to manipulate the "last used band". In multi-band products this paramater is used at startup to decide which band shall be searched first. In most cases the last used band is the most promising band to find networks in. Nevertheless, for testing purposes it is helpful to have influence on this decision.
If at startup no "last used band" is found in the memory, the "Default" setting (Europe or America) will be effective.
