NM2C ADJUSTMENT AND CALIBRATION PROCEDURES (continued)
5.4 Display Arm Tension Adjustments
5.4.1 Display Arm Hinge Adjustment:
5.4.1.1 Loosen the friction adjustment screw on the underside of
the display arm (no more than one turn). (It may be
necessary to raise or lower the arm to align the screw
with the access hole.) See Figure 5-4.
5.4.1.2 Raise and release the arm, and verify that it returns to
an approximately horizontal position.
Lower and release the arm, and verify that it returns to
an approximately horizontal position.
Contact the NAD Service Department if the display arm
fails to return to a near-horizontal position.
5.4.1.3 With the arm in a horizontal position, slowly re-tighten
the friction adjustment screw until the arm stays in
position when raised or lowered. (Do not over-tighten the
screw as this will cause the arm to loose tension in the
raised position.)
5.4.2 Machine Mount Joint:
5.4.2.1 If there is excessive free swing at the machine mount
joint, tighten the shoulder screw shown in the
illustration. The correct torque setting is 75 in. lbs.
5.4.3 Datagrip and Remote Display Assembly Torque Adjustment:
5.4.3.1 Remove the plastic cap at the end of the display arm to
expose the remote display assembly mounting screw.
5.4.3.2 While holding the remote display assembly, tighten the
mounting screw to a torque of 3 to 5 foot pounds.
5.4.3.3 Replace the plastic cap at the end of the display arm.
