32. Angular Velocity Sensor Sensitivity Adjustment
Adjust the gain to eliminate the output dispersion Angular veloc-
ity sensor.
Perform this adjustment when the lens block is replaced, CM-077
board is replaced, or Hall sensor is adjusted.
Do not perform this adjustment and check the Steady Shot opera-
tion only, if the microcomputer or board other than this lens block
failed.
32-1. Preparation when the angular velocity sensor or
the CM-077 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.

Note 1:The sensor sensitivity of SE7201 and SE7202 of the CM-
077 board is written only repair parts.
Preparation:
1) Read the PITCH sensor (CM-077 board SE7202) sensitivity
written on repair parts, and named this as P12.
2) Read the YAW sensor (CM-077 board SE7201) sensitivity writ-
ten on repair parts, and named this as Y12.

Note 2: Only the value of decimal places has been written to the
angular velocity sensor.

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.
