Note: The next two sections are presented on their own page. This makes it easy to remove the
page should you want to prevent other readers from knowing how to initialize the 601 or
bypass the front-panel security features.
4.11 Restoring Factory Presets
MM Caution
Do not reinitialize the 601 to the factory set values unless this is what you really
want to do. Reinitializing erases all user programs (presets 1 to 128) and there is
no way to recover your programs once you have done this.
You can reinitialize all programs to their factory set values by holding down the
load
switch
while applying power to the 601.
4.12 Disabling the Front Panel
Some applications may require disabling the front panel. Broadcasters using the 601 as their
on-the-air mic processor may want to make the unit impervious to adjustment.
The 601 has three levels of security:
None This is what you normally get when you turn the 601 on.
Partial Disables everything except the Wheel and the
load
button. Since no other buttons
operate, it is impossible to alter programs or to overwrite other programs.
Maximum Disables everything. Nothing on the front panel works.
To activate (or deactivate) any of the security features, turn the 601 off, press and hold one of
the following buttons, and turn the 601 on.
FILTER Enables no security. Everything is accessible.
RATE Enables partial security.
DEPTH Enables maximum security.
With partial or maximum security enabled, attempting to access any secured function results
in a LoC indication on the display. You can also defeat any security feature in effect by
reinitializing the 601.
Reinitializing erases
ALL user programs (presets 1-128).
The security features can be activated via MIDI. All 601 functions are always MIDI-accessible
regardless of the security level.
