Rear Panel Operations
The rear panel has a Reset button that initiates two levels of matrix switcher resets.
For different reset levels, press and hold the button while the switcher is running or
press and hold the button while you apply power to the switcher.
Performing an absolute system reset from the rear panel
This function is identical to the front panel system reset (see “Performing a system
reset from the front panel” on page 3-37) without requiring you to power down
the switcher. This function is also identical to the Esc ZQQQ SIS command (see
chapter 4, “Programmer’s Guide”). A system reset:
• Clears all ties and presets
• Clears all video and audio mutes
• Sets all input audio levels to unity gain (+0 dB)
• Sets all output volume levels to 100% (0 dB of attenuation)

Perform a system reset as follows:

Reset button until the rear panel Reset LED blinks three times (approximately
