changes in SETTING menu

It is not clear to me how I can see changes in the setting menu.
example 1
I want to change midi receiving channel to channel 7
procedure :
SETTING → MIDI (15) → 7 → SETTING
Is this correct ?
Is this immediate changed ?

example 2
Change midi input to DIN only
SETTING → CONFIG(16) → PAGE TO 3 ( 48) → 2 → SETTING
is this correct ?

Change midi send & receive channels to channel 7
SETTING → MIDI (15) → 7 (Channel) → SETTING

Change midi receiving channel to channel 7 and send to 1
SETTING → MIDI (15) → 7 (Input Channel) → Press & Hold 1 (Output Channel) → SETTING

Change midi input to DIN only: Location 3.4 Value 2
SETTING → CONFIG(16) → PAGE TO 3 (48) → 4 (Param) → 2 (Value) → SETTING

Changes are immediate
