3.      The Firmware Loader 

        The Firmware Loader gives you the chance to override the
        effects of an unsuccessful firmware upload, for example if the
        terminal adapter no longer reacts and you cannot enter any AT 
	commands (see below).
        A failure of the firmware is indicated by the continual blinking
        of the yellow "Line" LED, and the terminal adapter no longer 
	reacts to AT commands.
                                         
3.1     Installing the Firmware Loader

        To activate the Firmware Loader, you should upload the file
        Sloadtg1.upx with the programm ELSA ISDNconfig.
        
        IMPORTANT:
        DO NOT DISTURB your computer or terminal adapter while uploading
        the Firmware Loader !!!
     
------------------------------------------------------------------------

4.      Firmware Upload Guide

        A firmware update can be loaded into the Flash-ROM of your
        ISDN terminal adapter with the programm ELSA ISDNconfig. 

        IMPORTANT:
        DO NOT DISTURB your computer or terminal adapter while uploading
        the Firmware Loader !!!

------------------------------------------------------------------------

5.      Trouble Shooting


        -The upload fails without any transfer of data.

        Solution: You have chosen the wrong file for uploading.  Repeat
                  the upload and be sure to select the correct file.
