PWB AND ROM CHANGES FOR
PERFORMANCE ENHANCEMENT

1.Model name: JX610, JX600S, JX600

2.General: The control PWB and the ROM program are changed to enhance the following

performance.

3.Description: 1) Preventing mechanical noise from DC fan
A 100Ω resistor is inserted to the DC fan driving signal, though a 120Ω resistor is used
temporarily for the March production. With this change, two jumpers are added with
one circuit pattern cut

<Control PWB>

100Ω resistor added
(120Ω for the March production).
