	pole.
	• For a smaller or larger pole — Locally obtain a square
	U-bolt that fits your ceiling pole. The slotted holes on
	the bracket can accommodate a square U-bolt for pole

Using the PMK 350 Projector Mount Kit

The PMK 350 Low Profile Projector Mount Kit is an above- projector mounting kit that attaches to a 1" to 2" diameter projector mounting pole. It can hold more than one device, in a variety of sizes. The PMK 350 is available in black (part #70-563-02) or white (part #70-563-03).

Follow these steps to mount the YCS 100 on the PMK 350 bracket as follows:

1.	Remove the front and back panels from the
	PMK 350, using an Extron Tweeker or other small Philips
	screwdriver. (Retain the screws to reattach the plates when
	you are finished.)
2.	Remove any rubber feet from the bottom of the YCS 100.
3.	Secure the YCS to one side of the mounting bracket,
	using two of the supplied 4-40 x 3/16" screws in opposite
	(diagonal) corners.
4.	Using the two included tie wraps, strap the YCS power
	supply to the PMK 350 bracket.

5.Place the bracket around the projector ceiling mounting pole as shown in figure 2-10.

6.	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.
