Preparation:
1) Read the PITCH sensor (SY-169 board SE502) sensitivity writ-

ten on repair parts, and named this as S

502

.

2) Read the YAW sensor (SY-169 board SE501) sensitivity writ-

ten on repair parts, and named this as S

501

.

With the pins 1 and 2 of angular velocity sensor placed in the
lower position, read the data value.

Perform this adjustment only when replacing the angular velocity
sensor or lens block. When the microprocessor, circuit etc. is dam-
aged, don’t perform this adjustment but check the operations only.

Before adjustment, read the following data and record them.
When the SY-169 board is replaced, read out the data before the
replacement, and record them.

Reading out method:
1) Read out the data in Block:11, Page:61, Address:0E10, and

name this as Dp.

2) Read out the data in Block:11, Page:61, Address:0E11, and

name this as Dy.

The previous data (Dp, Dy) can be read from the SY-
169 board and it can be saved in the PC as a file by
using the Automatic Adjustment Program. (Refer to “8-
4. Angular Velocity Sensor Sensitivity Adjustment”)

Note down the sensitivity displayed on the angular 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 vi-
brate up and down or left and right during the steady shot operations.

The PITCH sensor and the YAW sensor are different parts.

The sensor incorporates a precision oscillator. Handle it with care as
if it dropped, the balance of oscillator will be disrupted and opera-
tions will not be performed properly.
