1) Execute SIM 65-1.

2) When the "+" section is pressed, it turns to gray. When all the four

points are pressed, the touch panel adjustment is completed and
the machine goes into the simulation sub number entry state.

In case of abnormality, the mode returns to the input mode.

*

Do not use a sharp pin or needle to press the "+" points.  

This adjustment must be performed in the following cases:

·

When the key touch sound volume is too small.

·

When the key touch sound volume is too great.

·

When the operation control PWB is replaced.

1) Remove the operation control PWB.

2) Turn the VR1 slider counterclockwise to set at about 135 degrees.

3) Use an actual machine and check the key input operations.

After this adjustment:

When the key touch sound volume is too small, turn VR1 clock-
wise.

When the key touch sound volume is too great, turn VR1 counter-
clockwise.

(Adjustment 1)

Hinge ass’y R hinge space dimension adjustment

(1)

Loosen the two fixing screws of SPF.

(2)

Loosen the nuts, turn the distortion adjustment screw and adjust
dimension T to 3.0 mm. 

(3)

Tighten two fixing screws of SPF and fix the hinge base. 

(4)

Fix the distortion adjustment screw with the nut. 

When the distortion adjustment screw is turned in the direction of X
(clockwise), the dimension T is increased. 

(Turn the distortion adjustment screw in the direction of X (clockwise),
and shift the SPF in the direction of arrow as shown above to adjust
the dimension T.)

When the distortion adjustment screw is turned in the direction Y
(counterclockwise), the dimension T is decreased.

±

 0.5 mm.

(2)

After adjusting the height, fix the height adjustment screw and
loosen the nut. 

When the height adjustment screw is turned in the direction of C
(clockwise), the dimension b is increased.

When the height adjustment screw is turned in the direction of D
(counterclockwise), the dimension b is decreased.

(Image distortion specification)

The right angle distortion of the short side for the long side must be
adjusted to less than 1.0 mm.

(Distortion pattern and adjustment)

1) Check which one of the copy image patterns 1 

~

 8 shown below is

like the copy image distortion. 

2) Follow the adjustment procedure according to the copy image

pattern. 

(Refer to adjustment 1, 2.) 

Note

1) When the hinge ass’y R height adjustment is performed, be sure

to perform adjustment (2) (Open/close sensor adjustment) again.
