ANL Switch - You can select the Automatic Noise Limiter to help reduce harsh background noise caused by a variety of interference sources. TX LED - An LED lights to indicate when the radio is transmitting. [. . . ] The most efficient and practical installation is a full quarter wave whip antenna mounted on the rear deck or fender top, midway between the rear window and bumper. A short "loaded" whip antenna maybe more convenient to install on your automobile, although the efficiency is less than a full quarter wave whip antenna. For marine installation, consult your dealer for information regarding an adequate grounding system and prevention of electrolysis between fittings on the hull and water. Ground Information Most newer U. S. and foreign made cars and small trucks use a negative ground system, while some older cars and some newer larger trucks may use a positive ground system. A negative ground system is generally identified by the "-" battery terminal being connected to the vehicle motor block, but if you cannot determine the polarity of your vehicle, consult your vehicle dealer for information. NOTE: This radio may be installed and used in any 12-volt DC negative or positive ground system. Negative Ground System If you are operating on a negative ground system, connect the red DC power cord from the radio to the positive "+" battery terminal or other convenient point and connect the black power lead to the chassis or vehicle frame, or the " -" terminal of the battery. Positive Ground System If you are operating on a positive ground system, connect the black DC power cord from the radio to the "-" battery terminal or other convenient point and connect the red power lead to the chassis or vehicle frame, or the positive "+" terminal of the battery. OPERATION Operating Procedure to Receive 1. Be sure that the power source, antenna and microphone are properly connected. Turn the unit on by rotating the volume control clockwise. Set the channel selector switch to the desired channel. Set the volume control to a comfortable listening level. Listen to the background noise from the speaker. Turn the squelch control clockwise until the noise disappears (no signal should be present). The receiver will remain quiet until a signal is actually received. Do not advance the control too far, or some weaker signals will not be heard. Be sure the operator has read and understands part 95, FCC rules and regulations prior to operating the transmitter. Select the desired channel for transmission. If the channel is clear, depress the push-to-talk switch on the side of the microphone and speak in a normal voice. CAUTION: The transceiver Voltage Standing Wave Ratio (VSWR) measurement must be performed prior to the use of the transmitter. A VSWR in excess of 2:1 may damage the transmitter. Please check your SWR reading frequently by using an SWR meter. Preventative Maintenance At six to twelve month intervals, the following system checks should be made: 1. Check the Voltage Standing Wave Ratio (VSWR). Inspect all screws and other mounting hardware. TROUBLESHOOTING If your PRO 510XL is not performing to your expectations, please try these simple steps.
