CM2C40 Installation Instructions

Bottom Cover Installation

After the CM2C40 has been properly configured for the display

and the display installed, the bottom cover height must be

adjusted to ensure proper fit into ceiling.

WARNING: IMPROPER INSTALLATION CAN LEAD TO

SEVERE PERSONAL INJURY OR DAMAGE TO

EQUIPMENT! Weight of bottom cover MUST NOT exceed

25 lbs (11.34kg).

To install the bottom cover :

1. Measure the distance between the bottom of bottom cover

mounting plate and the top edge of the opening in the ceiling

and record dimension for future use.

Figure 22

2. If the dimension identified during step 1 above is equal to or

less than the thickness of the bottom cover being installed,

the display travel limits must be adjusted before continuing

to avoid a collision scenario between the bottom cover and

the ceiling. Refer to step 6 below.

3. If the dimension identified during step 1 above greater than

the thickness of the bottom cover being installed, lower the

display using the remote control until locknuts securing right

and left cover adjustment brackets can be accessed. (See

figure 23)
