16. Angular Velocity Sensor Sensitivity Adjustment
• Perform the angular velocity sensor sensitivity adjustment only
when replacing the angular velocity sensor or lens block. When
the microprocessor, circuit, etc. malfunctions, do not perform
this adjustment but check operations only.
• Record the sensitivity label of the angular velocity sensor (re-
pair 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 opera-
tion. Be sure to take note of this.
Precautions on the Parts Replacement
There are two types of repair parts.
Type A
ENC03MA
Type B
ENC03MB
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,
readjust 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.
