The Items contained in group 1 (BST Monitor Items) are ALWAYS displayed within the menu,
as these items are critical for proper system operation. Therefore, the BST Monitor Items
Header itself is NOT displayed.
The Items contained in groups 2-5 are NOT DISPLAYED unless that particular item group has
been enabled from the C-More keypad.
