If the opening is not large enough, carefully cut or file as necessary until the sleeve easily slides into the opening. [. . . ] Locate the series of bend tabs along the top, bottom and sides of the mounting sleeve. With the sleeve fully inserted into the dashboard opening, bend as many of the tabs outward as necessary to firmly secure the sleeve to the dashboard. Place the radio in front of the dashboard opening so the wiring can be brought through the mounting sleeve. Follow the wiring diagram carefully and make certain all connections are secure and insulated with crimp connectors or electrical tape to ensure proper operation. After completing the wiring connections, turn the unit on to confirm operation (vehicle ignition switch must be on). If the unit does not operate, recheck all wiring until the problem is corrected. Once proper operation is achieved, turn the ignition switch off and proceed with final mounting of the chassis. Carefully slide the radio into the mounting sleeve making sure it is right-side-up until it is fully seated and the spring clips lock it into place. External PA Source Button The External PA source can be selected to broadcast the audio from a microphone. Using Microphones There are three microphone inputs on the back of the unit labeled Primary, Secondary and Tertiary. Each microphone has it's own level control located below the connector, which is used to adjust the volume level of the PA. If the secondary or Tertiary microphone is being used and the Primary microphone is keyed, only the Primary microphone audio will be heard in the PA. If the Tertiary microphone is keyed when the Secondary microphone is in use, the Secondary microphone will take priority over the Tertiary microphone (only the Secondary microphone will be heard). There are individual gain controls for each microphone on the rear of the unit. When a microphone is keyed, the audio from the Driver and Passenger modes will be muted and the audio from the microphone will be heard in the Driver, Passenger and EXT PA speakers. << Button Press the << (reverse) button to return to the previous chapter on a DVD or the previous track on a CD.
