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.

Press and hold the I/O button while you apply power to the switcher.
