Resetting the system to factory defaults
To reset a switcher to the factory default settings, press and hold the I/O button on
the front panel while applying AC power (figure 3-42). Continue to hold the I/O
button until all LEDs light and then release the I/O button. The power up
sequence completes (all LEDs turn off then turn on and off from left to right, the
Video and Audio LEDs turn on, and all other LED remain off). System reset does
the following:
• Clears all ties and presets.
• Clears all video and audio mutes.
• Sets all input audio gain levels to their default (0 dB) values.
• Returns the output audio level to the professional (+4 dBu) level.

Memory
The current configuration, all presets, and all input audio levels are saved in non-
volatile memory within 5 seconds of a change or exiting Audio Setup mode. When
power is applied, the last current configuration is retrieved. The previous presets
remain intact.
Wait at least 5 seconds after changing any configuration, saving a preset, or
exiting Audio Setup mode. Before 5 seconds have elapsed, changes that you
have made may not have been saved.
