What happens if I delete a listing from the Licensing & Registration Summary?
If you delete a listing from the Licensing & Registration tab, you will still be able to purchase new licenses for that communicator. If you registered your 375 Field Communicator, its information will still be present in the Online Licensing server, which is required to purchase licenses. However, you will be unable to use the optional Configurator in the Online view. Deleting a listing will not affect the operation of the 375 Field Communicator. You should delete a listing if the communicator is no longer used.
