power supply. Therefore, do not touch the back light holder to
avoid electrical shock.
Note 2: When replacing the LCD unit, be careful to prevent damages
caused by static electricity.

[Adjusting connector]
Most of the measuring points for adjusting the LCD system are
concentrated in CN002 of the Control Switch Block (FK).
Connect the Measuring Instruments via the CPC-9 jig (J-6082-393-
C, Note4). To operate the adjustment remote commander, connect
the power supply terminal of CPC-9 jig to the DC power supply
(6.0 to 7.2Vdc).
The following table shows the Pin No. and signal name of CN002.
Note 4: The old CPC-9 jig (Parts code: J-6082-393-B) cannot be used,
because it cannot operate the adjustment remote commander.
