[Adjusting connector]
Most of the measuring points for adjusting the LCD display are
concentrated in the following connector.
CN5501 of the PD-92 board (2.5"LCD model)
CN4501 of the PD-93 board (3"/3.5"LCD model)
Connect the measuring instruments via the multi CPC jig (J-6082-
311-A).
The following table shows the Pin No. and signal name of the
connector.
