SECTION 1

DISASSEMBLY (GR-DX Series)

1.1 BEFORE ASSEMBLY AND DISASSEMBLY

1.1.1 Precautions

• Be sure to disconnect the power supply unit prior to mounting and soldering of parts.

• Prior to removing a component part that needs to disconnect its connector(s) and its screw(s), first disconnect the wire(s) from the connector(s), and then remove the screw(s).

• When connecting/disconnecting wires, pay enough attention not to damage the connectors.

• When inserting the flat wire to the connector, pay attention to the direction of the flat wire.

• Be careful in removing the parts to which some spacer or shield is attached for reinforcement or insulation.

• When replacing chip parts (especially IC parts), first remove the solder completely to prevent peeling of the pattern.

• Tighten screws properly during the procedures. Unless specified otherwise, tighten screws at a torque of 0.088N

·cm). However, 0.088N·m (0.9kgf·cm) is a value at the

(0.9kgf time of production. At the time of service, perform the procedure at a torque 10% less than 0.088N

·m (0.9kgf·cm).

(See "SERVICE NOTE" as for tightening torque.)

1.1.2 Destination of connectors

Two kinds of double-arrows in connection tables respectively

show kinds of connector/wires.

1.1.3 Disconnection of connectors (Wires)

Wire

· Pull both ends of the connector in the arrow direction, remove the lock and disconnect the flat wire.

B-B Connector

· Pull the both ends of the board in the direction of the arrow, and remove the B-B Connector.

FPC Connector

· Extend the locks in the direction of the arrow for unlocking and then pull out the wire. After removing the wire, immediately restore the locks to their original positions because the locks are apt to come off the connector.

• Torque driver

Be sure to use to fastening the mechanism and exterior parts because those parts must strictly be controlled for tightening torque.

• Bit

This bit is slightly longer than those set in conventional torque drivers.

• Tweezers

To be used for removing and installing parts and wires.

• Chip IC replacement jig

To be used for replacement of IC.

• Cleaning cloth

Recommended cleaning cloth to wipe down the video heads, mechanism (tape transport system), optical lens surface.

1.2 ASSEMBLY AND DISASSEMBLY OF MAIN PARTS
