Reset button — The Reset button initiates two levels of reset to the
matrix switcher (see "Rear Panel Operations" in chapter 3, "Operation",
for details):

(approximately 9 seconds), then release the button and push it again.
This reset clears all ties and presets and resets all audio gains to 0 dB.
• Hard reset — Press and hold the Reset button while powering up the
switcher to perform all of the mode 5 reset functions and restore the
switcher to the default factory conditions.
AC power connector — Plug a standard IEC power cord into this connector to
connect the switcher to a 100 VAC to 240 VAC, 50 or 60 Hz power source.
