Installation procedure
Step 1
Remove the five rubber feet from the bottom of the recorder.
Use a screwdriver to remove the screws holding the rubber feet.

Step 2
Attach the rack handles (included) to the rack mounting brackets (included).
Fix them using the screws (included) (×4) and the washers (included) (×4) for the rack handle.
Tightening torque: 2.0 N·m ~ 2.4 N·m (1.48 lbf·ft ~ 1.78 lbf·ft)

Note:

• The rack mounting bracket (included) has two types of fitting holes to adjust the protrusion of the front rack. Use either of them depending on the installation conditions.

Fitting holes for the front position (about 15 mm {19/32 inches})

Step 3
Place the rack mounting brackets (included) on both sides of the recorder and fix them with the rack mounting bracket fixing screw (included) (×6).
Secure them using the rack mounting bracket fixing screw (included) (×6).
Tightening torque: 0.88 N·m ~ 1.08 N·m (0.65 lbf·ft ~ 0.80 lbf·ft)
