| UNIT 6: MULTI-CELL WIRELESS - LESSON 3: INSTALLATION & PROGRAMMING De-registering Portable Station Portable Stations can also be deregistered. This disables a previously registered Portable Station preventing it from being used on a system. There are two ways to de-register a Portable Station – 1) the system programmer can de-register a Portable Station 2) the system programmer can Forced De-register a Portable Station and then the Portable Station can delete the system that it is registered on. The difference between De-registering and Forced De-registering a Portable Station is based on the current communication status of the Portable Station. If a Portable Station is currently in-service and communicating with a Cell Station, the Portable Station can be De-registered. This removes the programming and registration information in both the Main Unit and the Portable Station. If a Portable Station is not in communication with a Portable Station, for example the Portable Station is turned off, or has removed the assigned system, the Portable Station must be Forced De-Registered in order to remove that Portable Station from system programming. The Forced De-Registered process removes the KX-TAW848 programming. The process can then be completed by removing the system assignment from the Portable Station by entering PS Programming-System Setting-Delete System and remove the system assignment from the Portable Station.
