Before installing, confirm your scanner fits in the desired mounting area and you have all the necessary materials. Your scanner requires a 2 x 7 1/8 x 5 5/16 inch (50 x 180 x 135 mm) mounting area. 1. Remove the four rear screws and pull off the black case before installing your scanner. 2. Install the DIN sleeve into the opening in your dashboard, lip facing out. 3. Push out the top and bottom tabs to hold the sleeve firmly in place. 4. Slide the scanner into the sleeve until it locks in place. Notes: To remove your scanner from the DIN sleeve, insert the two keys straight into the scanner’s front panel. Then, remove the scanner by pulling front panel. When mounting in your dashboard, you will need to connect an external antenna and an external speaker. mobile mounting in your vehicle You can mount your scanner under the dashboard, or on top of it, using the mounting bracket. 1. Attach the three protective rubber feet to the mounting bracket when you use the scanner on a flat surface. Do not use them when you mount the bracket with screws. 2. Use the supplied mounting bracket as a template to mark positions for the two mounting screws. 3. At the marked positions, drill holes slightly smaller than the screws. 4. Remove the paper backing from each washer and stick one inside of each bracket’s ear, aligning the washer’s hole with the bracket’s hole. 5. Attach the mounting bracket to your vehicle’s surface using the supplied screws and lockwashers. 20-428 Owner’s Manual Page 4 of 50 6. Slide the scanner into the bracket, aligning the scanner’s holes with the holes in the bracket, and then screw the mounting knobs into the scanner. Note: When drilling holes, be sure to avoid obstructions behind the mounting surface.
