※ Before Disassembly / (Re)assembly / Adjustment
On this lens, the VR (vibration-reduction) unit is mounted to correct the picture blur.
In order to maintain the functional accuracy of the picture blur correction, if detaching the VR
(vibration-reduction) unit and gyro base plate or if removing the main PCB unit, be sure to adjust the VR by
using the VR lens adjustment equipment (J15380）.
However, if disassembling the parts except the above, the VR adjustment is NOT necessary.
At service agencies where the "VR lens adjustment equipment" is not prepared, do NEITHER disassemble
NOR repair the products of the above case.
Caution:
① When disassembling, make sure to memorize the processing state of wires, screws to be xed and their types, etc.
② Because prototypes are used for "Disassembly/(Re)assembly/Adjustment", they may differ from the actual
products in forms, etc.
③ Because pictures are processed by a special method, they may differ from the actual ones in texture.
Points to notice for Lead-free solder products
・Lead-free solder is used for this product.
・For soldering work, the special solder and soldering iron are required.
・Do NOT mix up lead-free solder with traditional solder.
・Use the special soldering iron respectively for lead-free solder and lead solder.
They cannot be used in common.

If there is a problem with continuity between the contacts of the self-made tool and the relay FPC,

connect them.
2. Preparation of the lens for measurement

Assemble the MR-head-attached zoom index ring unit, the SWM, and the MF ring into the lens body.
Then connect the assembled lens to each measuring machines as follows:

In case the amplitude is small, disassemble up to

deformation is detected in the MR head, correct the
deform of the MR head. On the other hand, if such
correction is impossible or no deformation is detected,
replace the GMR sensor FPC unit. (Fig.2)
