1.CHANGE IN PATTERN OF THE CONTROL PWB.

2.VERSION UPGRADE OF THE CONTROL ROM.

1. Change in pattern of the control PWB.

1.Model name: JX330/M/P

Date: May. 26, 1995

REVISED

No. : CX-183 (R)

2.General: 2-1 The control PWB pattern has been changed from the start of February production
to improve productivity. In addition, to accommodate for vertical lines in the
display which occur as a result of this change, the following parts have been
either added or discontinued. (The additions and elimination of parts described
below have been carried out as a direct result of the change in the PWB pattern,
and therefore are not required for machines already out on the market.)

2-2 The core and core holder 2 on the control PWB side of the CCD cable have been

discontinued.

3.Description: 2-1 ➀ A jumper line has been added between pin 11 of IC42 (ACT86) and JPL37.

➁ A jumper line has been added between pin 65 of IC41 (GA3) and pin 12 of IC42

(ACT86).

➂ A pattern cut has been carried out on core 37 between pin 96 of IC29 (GA1) and

pin 65 of IC41 (GA3).

➃ The resistor (0Ω) at R224 has been discontinued, and a resistor (0Ω) has been

added at R225.

➄ A resistor (1KΩ) has been added at R221.
➅ Core L9 has been changed to a resistor (10Ω).
➆ The capacitor at C115 has been changed from 0.1µF to 0.01µF.
➇ Core L13 to L30 have been discontinued.
