10. Steady Shot Check
(CCD-TRV57/TRV57P/TRV67/TRV87/TRV87P)
Precautions on the Angular Velocity Sensor Replacement
There are two types of repair parts.
Type A ENC03JA
Type B 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, check
the steady shot operations.
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.
Steady Shot Check
Check the output of the angular velocity sensor.
