OPTIMOD-FM DIGITAL INSTALLATION
2-45
The RESTORE DEFAULTS button (in the Restore Defaults screen) restores
all System Setup and Input/Output parameters to their factory default
settings. It also erases all passcodes. You should never need to use this
button in an existing installation, although it is a convenient way to
make the 8600Si “factory fresh” if it is being installed in a different facil-
ity.
The RESTORE DEFAULTS button takes you to a screen that allows you to
keep or erase any user presets that exist in your unit.
