Dynamic Squelch Control (DSC): Automatically sets Squelch to optimal level for stronger signals. [. . . ] This transceiver may be installed and used in any 12-volt DC negative or positive ground system vehicle. GROUND INFORMATION Note: This transceiver may be installed and used in any 12-volt DC negative or positive ground system vehicle. and foreign made cars, and small trucks, use a negative ground system. Some older cars, and some new large trucks, use a positive ground system. With a negative ground system, the negative (-) battery terminal is usually connected to the vehicle motor block. If you cannot determine the polarity system of your vehicle, contact your vehicle dealer for information. Negative Ground System If you have a negative ground system, connect the red DC power cord from the transceiver to the positive (+) battery terminal or other convenient point. Then connect the black power cord to the vehicle chassis or negative (-) battery terminal. Positive Ground System If you have a positive ground system, connect the black DC power cord from the transceiver to the negative (-) battery terminal or other convenient point. Then, connect the red power cord to the vehicle chassis or the positive (+) battery terminal. 5 pc78ltw. qxd 2/24/99 8:24 AM Page 6 To Receive Be sure that the power source, antenna, and microphone are properly connected before proceeding.
