7. DISPLAY CHECK

This program is used to check the FL display section. The
display condition varies as shown below according to the
sub-menu operation.
The signal route is STRAIGHT.
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 al-
ternately (in lattice). (In the above example, the segments
in the second row from the top are shorted.)
