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 assembly and main board assembly. Check for mechanism driving section such as motor ,etc..
Disassembly method
Remove the bottom cover. Remove the front panel assembly. Remove the top cover . Install the front panel. Confirm that current is being carried by connecting an extension cord jig. Note Available to connect to the CP701 connector when installing the front panel. 1. 2. 3. 4. 5.

2. Pin Function I/O Function O Segment output pins used to display data transferred by serial data input. 53 to 55 COM1 to COM3 O Common driver output pins. The frame frequency is given by : t0=(fosc/384)Hz. 56 VDD -- Power supply connection. Provide a voltage of between 4.5 and 6.0V. INH 57 I Display turning off input pin. INT="L" (Vss) ----- off (S1 to S52, COM1 to COM3="L" INT="H" (VDD)----- on Serial data can be transferred in display off mode. 60 Vss -- Power supply connection. Connect to GND. 61 OSC I/O Oscillator connection. An oscillator circuit is formed by connecting an external resistor and capacitor at this pin. CLOCK 63 I Serial data interface connection to the controller. CL : Sync clock Pin No. 3 to 52 Symbol S3 to S52
