Brightness Submenu
The brightness of the HMI screen (LCD) display and HMI keypad can be individually adjusted to allow for changing ambient light conditions. The choices available to the operator are HIGH, MEDIUM, LOW, and OFF. OFF actually results in a very dim screen suitable for low light conditions.
Important Before replacing an HMI with no backlight, check
the Backlight feature to verify the backlight is turned on.
From the Standard Display, press the ACCEPT/ENTER center key. From the Main Menu screen select Brightness and press the ACCEPT/ENTER center key.
The Brightness submenu will appear. Select either LCD or Keypad and use the left or right keys to make a selection for brightness. When the desired brightness is shown, select ACCEPT.
