There are 8 programmable LEDs displayed as L5, L6, ..., L12 symbols on the
display. The LED Menu is accessed by hitting the Reset button once while on any
menu. Any activated LEDs will flash on the menu automatically.
One or more of the functions listed below are available for assigning to any of the
programmable LEDs. The label for the LED is set independently, as a LED may
represent several functions.
