[. . . ] --- Within each band, frequencies can be selected in 5 kHz increments, such as 28. 005 MHz in Band A or 29. 455 MHz in Band C. These are selected using the Frequency Selector knob after the band has been chosen. -Dual 7 Segment Frequency Display Frequencies are displayed on the Dual 7 Segment Frequency Display using a combination of numerical figures and decimal points. The figures indicate the first two values after the decimal point in the frequency, such as the 00 in 28. 005 MHz. The right hand decimal point in the display indicates whether the third value after the decimal point in the frequency is 0 or 5 -- if the right hand decimal is visible on the display, the third value is 5; if it is not visible, the third value is 0. The left hand decimal point in the display (between the two figures) indicates whether the two values before the decimal point in the frequency are 28 or 29 -- if the left hand decimal is visible on the display, the first two values are 29; if it is not visible, the first two values are 28. Refer to the examples in the following table.

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 ratio 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 Warning 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 PA / AM / FM switch to the desired AM or FM. 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. [. . . ] Pack radio securely to prevent damage in transit.
