Restore GMAC-5 factory settings
If desired, you can clear GMAC-5’s entire current configuration at any time and return the settings to the
factory default values. To do this:
•
Press and hold the Act button on the front panel for at least 20 seconds, until all three
status LEDs are on. Then release the button. The unit will restart with factory settings.
•
This procedure also returns the system user name and password to their original default
values of “admin” and “admin”.
