11.6 Mounting Screw Length Restriction

The AV-30-C is fastened to the instrument panel with four 6-32 screws. The
unit mounts from the rear of the instrument panel, with the screws being
inserted from the front of the panel.
The four 6-32 Mounting screws must observe depth limits given the
internal component design.
Torque screws to 6 (+/-1) inch-lbs.
The threaded hole in the AV-30-C bottoms out prior to the internal components.
Installing a mounting screw that is longer than optimal will not damage the unit
but will result in the unit not being fully fastened to the panel.
The installation kit contains multiple length screws to assist in compensating for
different instrument panel thicknesses.
Correct screw length may be determined by inserting the supplied screw in the
instrument panel (without the AV-30-C installed) and ensuring that either three
or four full threads are exposed on the opposite side of the panel. Select
alternate lengths as needed.
