The Owner Lock screen allows the owner of the unit to program a system and

then lock the unit against being reset. Individual OEM locked parameters

cannot be unlocked with the Owner Lock, and the owner cannot view OEM

locked parameters.
To enter Owner lock, change the lock status from OFF to ACTIVE. The unit

will always prompt for the default password, which is 'OMNI' for Owner lock.

Use the parameter wheel to cycle through characters, and the UP and DOWN

keys (or push the parameter wheel) to change position in the password. Once

the default password has been entered, press the STORE key to enter Owner

lock setup mode. The screens for any parameter can then be accessed in the

usual manner, turning the parameter wheel clockwise to lock the parameter.

Once the setup is complete, press the STORE key again to save the owner

lock setup. The unit will then prompt the user to enter a user password, and

then press STORE again to confirm and exit Owner lock setup.
To change Owner lock mode (from ACTIVE to OFF), the user Owner password

must be entered.

NOTE: There is no way to turn Owner lock off if the password has been

forgotten!

The Xover Adjust determines how crossover points are adjusted relative to the

corresponding edge of the adjacent band. The following options may be

selected:

BOTH

When set to BOTH, both the upper band edge of the lower band and the lower

band edge of the upper band are adjusted as a pair. This means that only one

filter adjustment is required to set a crossover point, and the graphic display

shows both edges moving together.
