Information for using a car audio service jig

1. We're advancing efforts to make our extension cords common for all car audio products.

Please use this type of extension cord as follows.

2. As a U-shape type top cover is employed, this type of extension cord is needed to check operation of the

mechanism assembly after disassembly.

3. Extension cord : EXTKSRT002-18P ( 18 pin extension cord ) For connection between mechanism assembl

and main board assembly.

Check for mechanism driving section such as motor ,etc..

Disassembly method

1. Remove the bottom cover.

2. Remove the front panel assembly.

3. Remove the top cover .

4. Install the front panel.

5. Confirm that current is being carried by connecting

an extension cord jig.

Note

Available to connect to the CP701 connector when in-

stalling the front panel.

Oscillator connection
An oscillator circuit is formed by connecting an
external resistor and capacitor to this pin.

Serial data transfer inputs.
Connected to the controller.
CE:Chip enable
CL:Synchronization clock
DI:Transfer data

Display off control input
INH= "L"(VSS) Display forced off

S1/P1 to S4/P4 = "L"
(These pins are forcibly set to the
segment output port function and held
at the low level.)
S5 to S68 = "L"
COM1 to COM3"L"

INH = "H"(HDD) Display on
However, serial data transfer is possible when
the display is forced off by this pin.

Used for applying the LCD drive 2/3 bias voltage
externally. Must be connected to VDD2 when a
1/2 bias drive scheme is used.

Used for applying the LCD drive 1/3 bias voltage
externally. Must be connected to VDD1 when a
1/2 bias drive scheme is used.

Power supply connection.
Provide a voltage of between 3.0 and 6.0V.
