You can use the hardware restore button on the Polycom HDX system to reset
the system in one of these ways:
• Restoring configuration-Restores the configuration, which resets most
system settings to default values.

• Factory restore-Completely erases the system and restores it to the
software version and default configuration stored in its factory partition.

system restores from the USB device instead of the system's factory
partition.
