2-0. CN NAME LCD Display Test
After starting, at the same time as the check mode is activated,
the back light of all Mini LCDs lights up and the check pattern
appears.
As the check pattern changes at every pressing of any switch,
check visually that there is nothing abnormal.
The table below shows the contents to be checked for each
check pattern.
Also, check for reversed contrast as described below during the
normal operation check or sound output check.
While viewing the NAME DISPLAY at the height barely
visible from the front pad, adjust the contrast (close to the
maximum) so that the display looks deep black. If it doesn’t
become deep black in that state but the NAME DISPLAY
viewed at the height barely visible from the opposite (rear)
side looks deep black, it is judged as NG because the angle of
visibility is reversed.
