2) When the ignition-starter switch is
turned on for the first time after the
connection, the meter gives out a buzz
sound momentarily, and the speedom-
eter, tachometer, fuel gauge, tem-
perature gauge, trip computer, and
warning lights come on. The warning
lights go out when the engine starts.
At this time the trip computer displays
all the letters and digits of the fluo-
rescent tubes. This is called the test
program condition. It occurs when the
ELECTRICAL SYSTEM
power supply to memory circuit turns
on. To restore the trip computer to
the normal condition, press any of the
four item buttons of the computer.
If the green wire is not connected as in
item 1), the memory circuit power
supply turns on each time the ignition-
starter switch is turned on. Therefore,
the test program is reproduced each
time the ignition-starter switch is
turned on.

3) When the lighting switch is turned
to the first or second step, the meter
face is illuminated, and the fluorescent
display tubes are dimmed to prevent
glare. The meter face brightness is
adjustable by the illumination control
switch. If this control switch is turned
farthest counterclockwise (to the
point of Click 2), the meter illumina-
tion is the brightest and the fluores-
cent display tubes are undiminished in
brightness. When the lighting switch
has to be turned on in the daytime, set
the control switch to the click 2
(second click) position.
