  • Page 3 JAA78151－R.3584.A ※BEFORE DISASSEMBLING, DISASSEMBLING AND ADJUSTING ①This lens loads the VR (Vibration Reduction) unit to perform the vibration reduction function. To maintain the accuracy of the vibration reduction function, be sure to perform the VR adjustment by using the VR lens adjustment equipment (J15380) when removing the VR unit and Gyro PCB. However, the VR adjustment is not necessary when disassembling the other parts.
