Before performing any of these functions with the local display
you must first ensure that the pushbuttons are placed in the
unlocked mode using ValVue. The positioner is provided in the
unlocked mode. See ValVue documentation for more details.
The SVI II AP offers several levels of accessibility. It may be
desirable, after initial setup, to lock the pushbuttons so that the
