The VR-09, VR-09B, and VR-730 all have an 'auto-off' feature that will power off the keyboard if it is not used for a certain period of time. By default this is set to 240 minutes, but can be changed to 10 minutes, 30 minutes, 240 minutes, or OFF:
- Press the MENU button.
- Turn the VALUE dial to select “System," and press ENTER.
- Use the CURSOR (^/v) buttons to select “Auto Off, and turn the VALUE dial to change the setting.
- Press EXIT several times to finish the procedure and return to the main screen.
