ADDITION AND ELIMINATION OF PARTS
1. Improved EMI levels
1.Model name: JX-9600/JX-9600PS 200V Series
2.General: To improve EMI levels, conductive tape and three capacitors have been added.
➀ Addition of conductive tape
To provide adequate EMI margins, the AC earth plate and the sensor earth plate have
been connected with conductive tape (12.5 x 120 mm).

➁ Addition of two 100pF capacitors and one 39pF capacitor to the ICU board
As a result of the presence of an additional condenser, the ICU PWB Units part code
has changed.

Add a 39pF ceramic
capacitor between the
CN 505 4A and 6B pins.
<Note>
Add an Irax tube to the
pin 4A capacitor pin
Cautions when attaching
1. Make the capacitor pin as
small as possible
2. Make sure no other pins or
parts are touched
Add 100pF ceramic capacitors between CN 505 pins 4A and 6A
Add 100pF ceramic capacitors between CN 505 pins 10A and 10B

2. Elimination of positioning pins and changes in transport springs
1.Model name: JX-9600, JX-9600PS
2.General: To improve productivity, positioning pins have been eliminated and changes have been
made in the transport springs. Spring screws have been added.

3. In detecting shield board changes
1.Model name: JX-9400, JX-9600, JX-9600PS
2.General: To improve productivity, the detecting shield board has been changed.
3.Effective time: October, 1993.
4. PCU board changes
1.Model name: JX-9400, JX-9600, JX-9600PS charger wire specs
2.General: Along with changing the PCU board CPU to masked ROM, the PCU board unit code
has been changed.
3.Effective time: July, 1993.
5. ICU board improvements
1.Model name: JX-9400
2.General: Jumper wires have been added and 3 pattern cuts have been made to prevent ➀) E4
errors from occurring when inserting and removing ICU board font cards, and ➁) left
margins going out of alignment.
