How does the CG button work?
The “CG” button on the head is for picking from a list of alternate Channel Guard (PL, CTCSS) tones, other than the one you have programmed for a particular channel. This is another non-obvious feature. The alternate “CG” button tone list you create will be the same for all modes. You create the list by pressing F2 when in the “Control Unit Personality” screen, and create a list of tones desired. STE = squelch tail eliminator, or reverse burst. Normally you would want this. After creating this list of tones, be sure to save the personality file when exiting (F10) or you will lose the list you just made. When actually using the head, press the CG button and then scroll through the various CTCSS tones using the CHAN up-down keys. CG-DEF means Channel Guard – Default Tone (the one you normally use on that channel.) CG-OFF or OFF means no tone, i.e. carrier squelch. Please note that each change of tone using this button requires the head to “re-download” to the radio with a brief delay. Th
