Note: The sensor sensitivity of SE500 and SE501 of the CD-168
board is written only on the repair parts.
Adjusting method:
1) Set data: 01 to page: 6, address: 00.
2) Read the sensor sensitivity written on SE500 of the CD-168
board, and take this as S
500.
3) Read the sensor sensitivity written on SE501 of the CD-168
board, and take this as S
501.
4) Calculate D
41´ and D42´ using the following equation (decimal
calculation).

41´ =
D
42´ =
5) Convert D
41´ and D42´ into hexadecimal digits, to obtain D41
and D42. (Round off decimal points)
6) Set data: D
41 to page: F, address: 41, and press the PAUSE button
of the adjusting remote commander.
7) Set data: D
42 to page: F, address: 42, and press the PAUSE button
of the adjusting remote commander.
Processing after Completing Adjustments
1) Set data: 00 to page: 6, address: 00.
2) Check that the hand-shake correction operations have been
performed normally.

16. Velocity Sensor Sensitivity Adjustment
• This adjustment is performed only when replacing the velocity
sensor.
Although this adjustment need not be performed when the circuit
is damaged, etc., check the operations.
• Note down the sensitivity displayed on the velocity sensor of the
repair parts. At this time, note down also to which board it was
attached to.
Be sure to check because if attached incorrectly, the screen will
vibrate up and down or left and right during hand-shake correction
operations.
Precautions on Parts Replacement
There are two types of repair parts.
For SE500: 1-801-731-31
For SE501: 1-810-725-71
If replace with other parts, the screen will vibrate up and down or
left and right during hand-shake correction operations. After
replacing, re-adjust according to the adjusting method after
replacement.
Precautions on Velocity Sensor
The sensor incorporates a precision oscillator. Handle it with care as
if it is dropped, the the balance of the oscillator will be disrupted and
operations will not be performed properly.
