16. Angular Velocity Sensor Sensitivity Adjustment
• Perform this adjustment only when replacing the angular
velocity sensor. When the microprocessor, circuit etc. is
damaged, don't perform this adjustment but check the
operations only.
• 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 the steady
shot operations.
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 steady shot 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.
