In this screen you can insert the numeric key to unlock the settings; the same screen appears when the "unlock"

Menu locking

In addition to the basic pushbutton locking function, a new menu locking strategy was introduced. There are three
levels of locking: All locked, Allow safe, Allow all.
All locked: only the menus for displaying infos are enabled, the other are hidden. Presets cannot be loaded.
Allow safe: user can change from Analog input to AES3 input, always with DSP into the signal path. Some common
DSP parameters can be changed (AES3 gain trim, main delay, DSP input selection)*.
Only local presets can be recalled, and they should be all safe for the speaker system connected to that amplifier
(example: HF driver 3 dB, HF driver 0 dB, HF driver +3 dB).
Allow all: all settings menus are enabled. User can recall presets from either local memory or smartcard.
