[. . . ] Set the switch to CH9 or turn Channel Selector knob to Channel 9. Press the microphone PTT switch and speak clearly. If there is no response, select an active channel and ask that party to relay your emergency broadcast on Channel 9. All channels, except Channel 9 may be used for normal communication. [. . . ] However, the efficiency of the short whip antenna is less than that of a full quarter-wave whip antenna. MARINE INSTALLATION Consult your dealer for information regarding marine installation. It is important to adequately ground the system and to prevent electrolysis between the fittings in the hull and the water. 4 UC343FH 10/23/03 2:32 PM Page 5 CONNECTING THE POWER CORDS We recommend connecting the power lead to the Ignition Switch Accessory Terminal. This way, the transceiver is automatically turned off when the ignition switch is turned off. Or, the power cord may be connected to an available terminal on the fuse block, or, to a point in the wiring harness. However, caution must be taken to prevent a short circuit. If in doubt, contact your vehicle dealer for information. This transceiver may be installed and used in any 12-volt DC negative or positive ground system vehicle. GROUND INFORMATION Most newer U. S. 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 UC343FH 10/23/03 2:32 PM Page 6 To Receive Be sure that the power source, antenna, and microphone are properly connected before proceeding. 1. Turn unit ON and set VOLUME Control to a comfortable level. 2. Set switch to NB/ANL. Dynamic Squelch Control automatically sets Squelch to the optimal level for stronger transmission and signal clarity. To scan for weaker signals, turn Dynamic Squelch Control off and perform the following steps: 4a. Turn SQUELCH fully clockwise so only strong signals can get through. 4b. Turn SQUELCH fully counter clockwise until you hear a hiss. Everything gets through - noise, weaksignals, and strong signals. 4c. Turn SQUELCH back clockwise until the hiss stops. Only clearer signals get through. 6 UC343FH 10/23/03 2:32 PM Page 7 Set SQUELCH only when the radio is not receiving a strong signal. 5. Adjust RF GAIN knob (small) to optimize reception in strong signal areas. 6. Adjust DELTA knob (small) to reduce or eliminate adjacent channel interference. 7.
