DISPLAY DIAGNOSIS

When RGB signal error occurred in the RGB system, tone of the color bar will change as follows.

When the color of the screen looks unusual, refer to AV- 1 6 0 , "Color of RGB Image Is Not Proper (All
Screens Looks Bluish)" , AV- 1 6 1 , "Color of RGB ImageIs Not Proper (All Screens Looks Reddish)" and
AV- 1 6 2 , "
Color of RGB Image Is Not Proper (All Screens Looks Yellowish)" .
VEHICLE SIGNALS

A comparison check can be made of each actual vehicle signal
and the signals recognized by the system.
CAUTION:
In case of confirming light signal, set D/N mode to ON/OFF
of lighting switch (normal setting).

OFF: D (Day mode)

ON: N (Night mode)
Unless above setting, light signal (ON/OFF) may not be
accurately displayed.
