14. Angular Velocity Sensor Sensitivity Adjustment
• This adjustment is performed only when replacing the angular
velocity sensor.
Although this adjustment need not be performed when the circuit
is damaged, etc., check the operations.
• 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
vibrate up and down or left and right during hand-shake correction
operations.
Precautions on the Parts Replacement
There are two types of repair parts.
Type A
ENC03JA or ENC03GA
Type B
ENC03JB or ENC03GB
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.
