I would try a Factory Reset of the keyboard.

Saves pouring thru menus trying to find what may have changed, sometimes things change inadvertently or even on their own over time.

From pg 41 of the User Manual:

Quote:

Here’s how to restore the settings of the PCR keyboard to the state they were in when
the product shipped from the factory.
1
Press the [EDIT] button so it’s lit.
The display will indicate “EDIT.”
2
Use the VALUE knob to select “SYS,” and press the [ENTER] button.
3
Use the VALUE knob to select “SY16,” and press the [ENTER] button.
4
“RST” will be blinking in the display; press the [ENTER] button.
5
“YES” will be blinking in the display; press the [ENTER] button.



Fingers Crossed,
