If a handset is subscribed to two systems only, you can use Auto Login B to change between the two systems auto-
matically. The selected system is marked with a "B".
Please note: Auto login B can be used in separate systems which are overlapping each other. As soon as the hand-
set has measured a low radio signal 5 times in succession, it will start up the Auto login B procedure and change to
an alternative system if available. Changing between two systems can only take place while on hook. Any call will
be dropped when changing to an alternative system.
