9. CAMERA Adjustment 7
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.
9-1. Precaution before adjustment
Before adjustment, read the following data and record them.
When the SY-170 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.
9-2. Preparation when the angular velocity
sensor or the SY-170 board is replaced
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.
Precautions on the Parts Replacement
The PITCH sensor and the YAW sensor are different parts.
Precautions on Angular Velocity Sensor
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.

Adjustment Address 0E10, 0E11
Note: The sensor sensitivity of SE501 and SE502 of the SY-170
board is written only repair parts.
Preparation:
1) Read the PITCH sensor (SY-170 board SE502) sensitivity writ-
ten on repair parts, and named this as S
502
.
2) Read the YAW sensor (SY-170 board SE501) sensitivity writ-
ten on repair parts, and named this as S
501
.

How to read the sensitivity data of angular velocity sen-
sor
With the pins 1 and 2 of angular velocity sensor placed in the
lower position, read the data value.
