Page 109 SECTION 1 JIGS AND TOOLS TOOLS REQUIRED FOR ADJUSTMENTS 1. Torque driver Torque driver Be sure to use to fastening the mechanism and exterior parts YTU94088 YTU94088-003 because those parts must strictly be controlled for tightening torque. Torque setting value of torque driver is limited. At the values over the maximum torque setting value, fasten a screw manually not to damage the screw thread.
Page 110 SECTION 2 SPECIFIC SERVICE INSTRUCTIONS 2.1 DVC MECHANISM 2.1.1 Precautions (1) When fastening parts, pay careful attention to the tighten- ing torque of each screw. Unless otherwise specified, tight- en a screw with the torque of 0.055 N•m (0.56 kgf•cm). (2) Be sure to disconnect the set from the power supply before fastening and soldering parts.

Page 130 VHS-C MECHANISM 2.2.1 Precautions (1) When fastening parts, pay careful attention to the tighten- ing torque of each screw. Unless otherwise specified, tight- en a screw with the torque of 0.216 N•m (2.2 kgf•cm). Torque setting value of torque driver is limited. At the val- ues over the maximum torque setting value, fasten a screw manually not to damage the screw thread.
