TRIM RING INSTALLATION:
Note:
This page only covers special installation considerations for thick trim ring installation. If the video
monitor is to be installed in a vehicle with the thick trim ring, it may need to be trimmed to fit the contour of the
vehicle Headliner.
Note:
The trim rings supplied with this unit are not designed to be trimmed.
1)
In this installation, the video monitor is mounted directly to the overhead cross-member in the roof
using the mounting screw bosses. These screw bosses should contact the cross-member directly
(i.e.: no gap between the screw boss and the roof structure). Also, be sure that the screws do not pierce
the outer roof skin when fully fastened to the cross-member. The trim ring is attached to the video
monitor using the perimeter screw bosses. It is important that the screws used in this installation are
not over tightened, and that the video monitor and trim ring are mounted in such a way that the
assembly does not distort (or bend) when the mounting screws are tightened. An alternate method is to
use the mounting bracket. First secure the mounting bracket to the cross-member, then screw the
monitor into the mounting bracket. See the drawing in this manual.
2)
It is best to mount the video monitor to the roof structure without the trim ring first. There should be a
gap between the headliner and the outer flange of the video monitor. The trim ring should be cut to fill
this gap. Apply masking tape to the outer surface of the trim ring in the areas where the cut will be made.
3)
Mark the cut to follow the necessary contour of the roof. The suggested method of marking is as
follows:
A)
First mark the narrowest point of the trim ring on the masking tape. Be careful to consider not only
vertical location, but fore-aft location.
B)
Using the handle of a screwdriver, make a “transfer marking tool”. See diagram below. Place the
tool against the roof and the marker against the masking tape on the trim ring. Trace the cut to be
made around the entire perimeter of the trim ring.
C)
Cut the trim ring using a sharp utility knife or shears. Make the cut in several passes over the
marked line, each time cutting a little deeper. It is not necessary to cut completely through the
plastic, the cut only need be over 50% of the wall thickness of the plastic. By bending the cut back
and forth several times, the plastic will break cleanly at the cut.
D)
Check the fit of the trimmed console and make any minor adjustments necessary.
4)
The trim ring can be painted or covered with a material that matches the headliner before assembling
the trim ring to video monitor.
5)
The finished trim ring should be attached to the video monitor, then attach the assembly to the roof.
