Turning the <Data> wheel will select the preset you wish to load at initial reset.

Press the <Preset> button again when the selection is complete. Normal resetting will continue.

System Lock Out

Press and hold <AFS> at power-up until one of the following messages appears (depending on the current state of system lockout):

System Unlocked All user input will be accepted <AFS> to exit

or

System Locked! No user input will be accepted <AFS> to exit

or

Filter Unlocked. Filter clear will be accepted <AFS> to exit

Use the <DATA WHEEL> to select the desired state and then press the <AFS> button to continue booting in the selected state.

The “System Unlocked” state allows normal operation.

The “System Locked” state is the complete lockout state. No user button input of any kind will be acted upon.

The “Filter Unlocked” state is the same as the “System Locked” state except that the <PRESET> and <AFS> buttons are accepted. Pressing <AFS> once will go to the AFS edit page with the “Clear” parameter set to “LIVE” and the cursor on the third parameter “Clear w/ <AFS>”. Pressing and holding the <AFS> button will enable a filter clear. After the clear, the DriveRack PX will return to the preset screen.

Locked operations will cause a “LOCKED” icon to appear in the upper right corner of the screen for a few seconds.
