17. Velocity sensor sensitivity adjustment
CCD-TR96/TR916 MODEL
CCD-TR620E/TR720E/TR740E MODEL
The “Velocity Sensor Sensitivity Adjustment” is necessary only
when the gyro sensor is replaced. If microprocessors or circuit board
is not replaced, this adjustment is not necessary. Make operation
check only.

Adjustment address 5A, 5B
Specified value Shoot an arbitrary object at TELE
end, and confirm that the
STEADYSHOT function works
correctly.
Adjustment procedure:
Note 1 : Caution when replacing parts
The two types of parts : ENC05GA and ENC05GB are
supplied. Use the same type of sensor as that of the
defective sensor. If different type of either ENC05GA or
ENC05GB is used, picture can vibrate vertically or
horizontally during camera-shake correction. After
replacement, make adjustment as described.
Note 2 :
Caution on angular speed sensor
The angular speed sensor has high precision vibrator
inside. If the sensor is dropped, balance of the vibrator is
lost resulting in faulty operation. Handle the sensor
carefully.
