During the transmission of the upgrade file, a series of dots will scroll across
the screen, feedback from the DS-100 Data Switch that the upgrade is going
smoothly. If the upgrade fails after the first few dots appear, go back and
reset the Line delay to 300 milliseconds.
If you could see the front panel of the DS-100, you would see the Power and
Ports LED’s blinking during the upgrade. The upgrade should take about 5-6
minutes, hit <ESC> to start the DS-100 with the upgrade when the message
appears. If you wait longer than 60 seconds, the DS-100 will start the
upgrade by itself.
You have now completed the upgrade.
The final menu item is 99, which is used to exit the programming mode.
Forced exit will occur if the Programming Inactivity Time-out expires, see
