ONITOR IN A PLACE WITHIN THE DRIVER S VIEW THIS IS NOT ONLY DANGEROUS BUT IT IS ALSO ILLEGAL Once the mounting location of the monitor has been determined there may be additional preparation work necessary depending on the vehicle structure and installation method Some of the steps that may be required are A Removal of the vehicle s dome light B The headliner may need to be trimmed TRIM RING INSTALLATION If the video monitor is to be installed with the trim ring you may want to remove the rubber gasket first See the drawing below Rubber Gasket 1 Lay the MMD85A down on a soft surface to avoid scratching the unit Grasp the rubber gasket above the DVD slot and pull it off in a circular motion Refer figure 1 Figure 1 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 overtightened and that the video monitor and trim ring are mounted in such a way that the assem bly does not distort or bend when the mounting screws are tightened The trim ring MUST be screwed to the unit Refer figure 2 Trim Ring 3 The MMD85A is now ready to be mounted in the vehicle Refer figure 3 Figure 3 MOUNTING THE TRIM RING n TTT i Roof Support Headliner Mounting Bracket G Je 4 Self Tapping Screws not supplied lt T______ Video Unit LL 5 8 Flat Washers
