vi.

Pivot the arms so that they extend towards

 

the center of the projector (see the figure at

 

right). Adjust the arms as needed for your

 

projector model.

 

NOTE: Avoid overlapping the arms where

 

possible.

vii.

With the security flange towards the rear of

 

the projector, place the projector bracket on

 

top of the arms and adjust for slot alignment.

Using the slots on the bracket that are

closest to the barrel on each arm, place the

clamp under the arm and lightly secure it to the

bracket with the adjustment screws (see the

figure at right). Loosely secure all the mounted

arms.

NOTE: Where arms are unavoidably

crossed, replace the original adjustment

screw with a supplied 10-32 ¾ inch

adjustment screw and secure both

arms to the bracket using one clamp. In

addition, the barrels on the arms must be

raised to compensate, keeping the arms

level and reducing stress.

viii.As close as possible, balance the weight of the projector evenly across the projector bracket. Lift the bracket at opposite corners to assess if the configuration is approximately balanced.

ATTENTION: Take into consideration the uneven weight distribution of the projector when lengthening or shortening the arms. Distribute the projector weight evenly on the arms.

Adjust the bracket on the arms as needed. The projector shown at right is as close as possible to being evenly balanced.
