Precautions for AV Control Unit Replacement

NKS001CG

The AV control unit has the following information stored in its memory. Record the memory contents before
replacing the control unit, and input them in the new unit as necessary. 

NOTE:
Only removing the battery does not erase the memory.

Precautions for LCD Monitor

NKS002JH

●

When passenger compartment temperature is low, the LCD monitor sometimes dims because of the
brightness of the back light (small fluorescent light) integrated into the LCD monitor decrease. In this case,
the refreshing rate of the picture also becomes low because of the low response of the LCD monitor.
When passenger compartment becomes warm, however, the LCD recovers the normal display.

●

Sometimes, black or bright dots peculiar to LCD monitor can be seen on the display.

●

Back light sometimes flickers or darkens according to the total consumption hours and the number of ON
and OFF switching. In this case, the back light should be replaced (LCD monitor assembly).
