Don’t be afraid to experiment with the buttons and

controls on the DriveRack PA. It is recommended

that you familiarize yourself with these controls

before connecting the device to your system. Once

you feel comfortable with the navigation of the unit

you can easily perform the Factory Hard Reset

procedure (as described in the back of the Owner’s

Manual). This Hard Reset will set the device back to

it’s factory default state.

Enjoy!
