When used to tune the antenna or monitor the quality of the coaxial cable and RF electrical connections, the needle swings proportionally to the ratio of standing wave voltage and RF output. If there is any degradation in these, due to humidity, salt, spray, vibration or corrosion, the SWR meter reading will rise, thereby indicating that a problem exists. --RX / TX Indicator This indicator glows green when in receive mode and red when in transmit mode. Antenna Indicator This indicator glows red whenever the standing wave ratio is greater than 3 to 1. -- Operating to Receive To begin operating your radio: 1. Be sure the power source, microphone and antenna are properly connected. Turn the unit on by turning the volume knob clockwise and set the volume for a comfortable listening level. Set the CW / FM / AM / USB / LSB switch to the desired mode. Set the RF gain control fully clockwise for maximum RF gain. Listen to the background noise from the speaker, then turn the squelch ring slowly clockwise until the noise just 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 of the weaker signals will not be heard. Select the desired frequency with the band and frequency selector knobs. Adjust other controls as desired. Microphone · The receive and transmit modes are controlled by the Press-To-Talk (PTT) switch on the microphone. Press the switch to transmit, release it to receive. When transmitting, hold the microphone two inches from the mouth and speak clearly in a normal voice. To substitute for the supplied low-impedance (500 ohm) dynamic microphone, see the alternate microphones and installation section on page 17. Operating to Transmit To transmit a signal: 1. Select the desired frequency for transmission if different from the one chosen to receive. [. . . ] Pack radio securely to prevent damage in transit. If possible, use the original packing material.
