Performing a System Reset from the Front Panel

The front panel reset is identical to issuing the EZXXX} SIS command defined on page 104. A system reset performs the following functions:

•Clears all ties and presets

•Clears all video and audio mutes

•Resets all I/O grouping

•Resets all RGB delay to 0 seconds

•Resets all input audio levels to unity gain (0 dB)

•Sets all output volume levels to 100% (0 dB of attenuation)

NOTES:

•System reset does not reset the Internet protocol (IP) settings or replace user- installed firmware.

•The system reset clears most image and audio adjustments. To save these settings, use the Windows-based Matrix Switchers Control Program and the File > Save MATRIX settings as... selection (see page 124) before you perform this reset.

•If background illumination was turned on before the reset, the I/O and control buttons are unlit after the reset. But, when you cycle power, background illumination returns to as selected.

Reset the switcher to the factory default settings by pressing and holding the RGBHV (CrossPoint switchers) or Video (MAV Plus switchers) button and Audio button simultaneously while you apply AC power to the switcher (see figure 53).

Press and hold the buttons while you apply power to the switcher.
