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.

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.
