Installation and Operation, cont’d

5.

If desired, remove the back panel of the PMK 350 and

 

mount an additional IR 102 Rx or other device(s) at the

 

back of the bracket, as described in step 3 on the previous

 

page.

6.

Place the PMK 350 mounting tray around the projector

 

ceiling mounting pole. (See the illustration on page 1-9.)

7.

Assemble the U-bolt and the following parts in the order

 

they are listed below:

a. Pass the legs of the U-bolt through the slotted holes on the back of the mount plate flange.

b. Place the U-bolt legs around the ceiling pole.

c. Pass the U-bolt legs through the round holes in the contoured base.

NPlace the contoured base against the pole and opposite the mount plate flange. The pole should fit snugly into the depression in the center of the contoured base.

d. Pass the U-bolt legs through the round holes in the L-shaped bracket.

8. Align the two round 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-shaped 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-shaped bracket to adjust it as needed.
