Precautions on the Parts Replacement
There are two types of repair parts.
There are two types of repair parts.
Type A: ENC03JA
Type B: ENC03JB
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 operation according to the following method.

right during hand-shake correction operations. After replacing, check
the steady shot operation according to the following method.
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.

[Adjusting connector]
Most of the measuring points for adjusting the viewfinder system
are concentrated in CN713 of VC-272 board.
Connect the Measuring instruments and the adjustment remote
commander via the I/F unit for LANC control (J-6082-521-A) and
CPC jig connector (J-6082-539-A) to CN713. To operate the
adjustment remote commander, connect the AC power adapter to
the DC IN jack of I/F unit for LANC control, or connect the L
series Info-LITHIUM battery to the battery terminal of I/F unit for
LANC control.
The following table shows the Pin No. and signal name of CN713.
