6.	Pass the two legs of the U-bolt through the following parts in the order they
	are listed below:
	a.	The slotted holes on the back side of the PMK 350 mount plate (then
		around the ceiling pole)
	b.	The round holes in the rubberized contoured base
	c.	The round holes in the L bracket
7.	Place the rubberized contoured base against the pole and opposite the back
	plate. The pole should fit snugly into the depression in the center of the
	contoured base.
8.	Align the two holes in the bottom of the L bracket with the two slotted holes
	in the base of the PMK 350, on either side of the opening for the pole; and
	attach the L bracket to the base by inserting the two provided 6-32 x 5/16"
	screws through the aligned slots. Tighten the screws slightly; you should
	still be able to slide the L bracket to adjust it as needed. (See the illustration
	below.)

9. Move the PMK 350 up to the desired location on the ceiling pole, as close to the ceiling as desired.

10. Secure the L bracket to the U-bolt, using the included hex nuts. Hand-tighten the hex nuts, make any final adjustments to the PMK’s position, then tighten the hex nuts securely, using an 11/16" deep socket or box-end ratchet wrench.

NBe sure to tighten the hex nuts securely enough that the PMK 350 does not slide down the ceiling pole. It is recommended that you use a socket wrench to tighten them.

11. Tighten the L bracket screws securely, using a Philips #2 screwdriver.

12. Secure the front panel to the mounting tray with four of the included #6 screws.

13. If desired, tear out one of the four perforated self-adhesive overlay sheets and apply it to the underside of the mounting tray.
