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 (see figure 17). 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 LEDs 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.

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.

NOTE: 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.
