Resetting the Controller
There are four reset modes (numbered 1, 3,4, and 5 for the sake of comparison with other
Extron IPL products) available by using the Reset button (b) on the front panel. The Reset
button is recessed, so use of a pointed stylus, ballpoint pen, or Extron Tweeker is suggested.
CAUTION: Review the reset modes carefully. Use of the wrong reset mode may result in
unintended loss of flash memory programming, reassignment of ports, or a
unit reboot.
