Front and Rear Cover Separation
Lay the radio face down and loosen the four (4) Torx screws (A) on the back of the radio; complete screw re- moval is not necessary. See Figure 6. Separate the covers by carefully lifting the Rear Cover Assembly
When reassembling the unit, verify the rubber gasket surrounding the perimeter of the cover is in good condition and it is in the groove. Also verify the connector pins align properly. For proper operation, the screws should be tight- ened so there is no gap between the covers. It is recom- mended that the top screws be tightened first while squeezing the radio together to ensure the gap is completely closed. The bottom screws can then be tightened.
