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.

Note:
The sensor sensitivity of SE301 and SE302 of the CD-193 board is
written only on the repair parts.
Adjusting method:
1)
Select page: 6, address: 00, and set data: 01.
2) Read the sensor sensitivity written on SE301 of the CD-193
board, and take this as S
301
.

board, and take this as S
302
.
4) Calculate D
41
' and D
42
' using the following equation (decimal
calculation).
NTSC model: D
41
' = 60/S
301
D
42
' = 5F/S
302
PAL model:
D
41
' = 80/S
301
D
42
' = 7F/S
302
5) Convert D
41
' and D
42
' into hexadecimal digits, to obtain D
41
and D
42
. (Round off decimal points)
6) Select page: F, address: 41, set data: D
41
, and press the PAUSE
button of the adjustment remote commander.
7) Select page: F, address: 42, set data: D
42
, and press the PAUSE
button of the adjustment remote commander.
Processing after Completing Adjustments:
1)
Select page: 6, address: 00, and set data: 00.
2) Check that the steady shot operations have been performed
normally.
