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

Fig.3-1-1
1.1.4 Tools required for disassembly and assembly
Fig.3-1-2
•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
1.2.1 Assembly and disassembly
When reassembling, perform the step(s) in reverse order.
(∗1) Order of steps in Procedure
When reassembling, preform the step(s) in the reverseorder.
These numbers are also used as the identification (location)

[Example]
• 4 (S1a) = Remove four S1a screws.
• 3 (L1a) = Disengage three L1a hooks.
• 2 (SD1a) = Unsolder two SD1a points.
• CN1a = Remove a CN1a connector.

2.1 BEFORE ASSEMBLY AND DISASSEMBLY
2.1.1 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 0.078N·m
(0.8kgf·cm). However, 0.078N·m (0.8kgf·cm) is a value at the
time of production. At the time of service, perform the
procedure at a torque 10% less than 0.078N·m (0.8kgf·cm).
