3.2 Mounting Requirements
3.2.4Notes on mounting
(1)Mounting frame structure and clearance
a)For vibration resistance and heat dissipation, this optical disk drive uses an embossed structure as shown in Figure 3.6, as well as a frame which has a construction similar to other frames which perform the same function.
b)As shown in Figure 3.6, the inward projection of the mounting screw from the outer surface of the drive frame must not exceed 3 mm.
c)The clearance between the external surface of the drive frame and the user's frame structure must be at least 1.5 mm.
d)The clearance between the top and bottom surfaces and the user's frame structure must be at least 1.5 mm.
e)When mounting the optical disk drive, the screw tightening torque should be 0.4 to 0.45Nm (4 to 4.6kgcm).
f)When the optical disk drive (with panel) is mounted in a locker, there should be no deformation of the mounting fittings provided and the optical disk drive's panel should not be deformed. If the drive is used with the panel deformed, ejection of the cartridge will be faulty. Check if the door will close from any position whatever when the optical disk drive is installed.
