SMX System MultiMatrix Switcher • Operation 31
Using Reset Levels
The SMX can be returned to default settings by choosing certain reset modes. This can be
done via the front panel or the recessed Reset button on the rear panel (see c on page 8).
Using the Front Panel
The front panel reset is identical to the EZXXX} SIS command (see the Reset
Switcher SIS command on page 51). This clears all ties, presets, and mutes; resets all
RGB delay to 0 seconds; resets all input audio levels to unity gain (0 dB); and sets all output
volume levels to 100% (0 dB of attenuation).
NOTES:
• This system reset does not reset the Internet protocol (IP) settings or replace
user-installed firmware.
• To save settings, use the SMX Control Program and the File > Save MATRIX
settings as...
command (see Save MATRIX settings as... on page 63).
To initiate the reset, perform the following:
1. If necessary, disconnect the power.
2. Press and hold the View and Esc buttons while reapplying AC power to the SMX.

3. Continue to hold the View and Esc buttons until the SMX properly powers up (see
Powering Up on page 16) and then release the buttons.
Using the Rear Panel
The recessed reset button on the rear panel initiates four levels of resets (numbered 1, 3, 4,
and 5). Use a pointed stylus or Extron Tweeker to press it and select a reset level (see the
Reset Modes Table on page 32 for the modes). If the reset button is continuously held
down, the I/O light blinks every 3 seconds as the next reset level is reached, corresponding
to modes 3, 4, and 5. Use mode 1 if compatibility issues arise with user-loaded firmware.
ATTENTION: After a mode 1 reset is performed, update the firmware to the latest
version. Do no operate the SMX with the firmware version that results from the mode 1
reset. To use the factory default firmware, upload that version again.
If mode 1 is selected by mistake, cycle power to the SMX to return to the firmware version
that was running before the reset. Use the 0Q SIS command on page 45 to confirm that
the factory default firmware is no longer running (look for the asterisk [*] following the version
number).
• Use mode 3 to restart the communication and control events.
• Use mode 4 to reset most IP protocols to their default settings.
• Use mode 5 to restore the switcher to the default conditions.
