Lock menu

Back

Returns to the options menu.

Lock all

This function locks all settings of the DDP except for the mute functions in

the main menu. All menus in which settings can be examined remain

accessible.

Lock presets

This function locks only the settings that can change a system preset. This

means that besides the system presets, also the user presets cannot be

recalled and also the DDP cannot be switched to another operating mode

(dual channel mode, stereo mode, bridged mono mode or 2-way active

mode). All other settings are still accessible.

After selection of the Lock all or the Lock presets function the DDP asks for

your lock-code. The lock-code is factory set at 0000.

Change code

To change the factory set lock code from 0000 to your own code, or to

change the lock code you use the change code function. The DDP asks for

the current lock code and after that for the new lock code.

Unlock

If the DDP is locked by either the Lock all or the Lock presets function, the

Unlock menu item is displayed. To unlock the DDP, select this function. The

DDP asks for the lock-code and will then suspend the lock function.
