2. DISPLAY

This menu is used to check the FL display.
Segment conditions of the FL driver and the FL tube are checked by turning ON and OFF all segments.
Next, the operation of the FL driver is checked by using the dimmer control.
Then a short between segments next to each other is checked by turning ON and OFF all segments alternately (in
lattice).
(In the above example, the segments in the second row from the top are shorted.)
