About this task
The A421 Control buttons and display operate the same way in Basic and Advanced
menus. The parameter code flashes on and off in any parameter code screen.
Procedure
To navigate through all of the parameter code screens, press
Down or Up.
To exit either menu and return to the Main screen, press
Down and Up
simultaneously.
While in any parameter value screen, the parameter value flashes on and off.
To scroll through all of the available parameter values for the associated
parameter code, press Down or
Up.
With the preferred parameter value displayed, press MENU
to save the value and go to the next parameter code screen.
Note: If you do not press MENU to save a new value, the control reverts
to the last saved value. After 30 seconds of inactivity, while in any screen, the control reverts to the Main
screen.
