12. Steady shot adjustment
• Perform the steady shot adjustment only when replacing the
angular velocity sensor. When the microprocessor, circuit, etc.
malfunctions, do not perform this adjustment but check operations
only.
malfunctions, do not perform this adjustment but check operations
only.
• Record the sensitivity label of the angular velocity sensor (repair
part), including to which side of the board it was attached to, etc.
If it has been attached incorrectly, the image will move up and
down or to the left and right during steady shot operation. Be sure
to take note of this.

to take note of this.
Precautions on the Parts Replacement
There are two types of repair parts.
Type A ENC03EA or ENC03JA
Type B ENC03EB or ENC03JB
Replace the broken sensor with a same type sensor. If replace with
other type parts, the image 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 Angular Velocity Sensor
The sensor incorporates a precision oscillator. Handle it with care
as if it dropped, the balance of the oscillator will be disrupted and
operations will not be performed properly.
