Precautions on the machine monitor display
The liquid crystal display panel may have black
q
spots (which do not light up) or bright spots
(which stay on).
Products having 10 or less black or bright
spots conform the product specification; such
the condition is quite normal.
q Battery voltage may suddenly drop at engine-
start due to ambient temperature or the condi-
tion of the battery. The machine monitor dis-
play may temporarily disappear if it happens; it
is quite normal.
Continuous operation of the machine monitor
q
may display blue bright spots on the screen
having a black background; it is quite normal.
The screen normally displayed on the monitor
has a blue or white background. For this rea-
son, blue spots will not cause any problem
(since the liquid crystal lights up red, blue, and
green spots when displaying white).
