Would like to scan programmed channels
The person who programmed your radio decided if and how the channel scanning would function, and whether or not the person using the radio would be able to program a scan list, and if so, which switches or buttons to use. It was all determined using computer software and by connecting the computer to the radio. Maybe you have a 3-position switch. Maybe by putting the switch in a certain position, you can program the scan list yourself. Maybe when the switch is in the right position, then pressing a side button turns on a green light to indicate that you've just added that channel to your scan list. Pressing the same side button again turns off the green light to indicate that you've just removed that particular channel from the scan list. Do this for all 16 channels, then put the 3-position switch into the scan-on position. Instead of a 3-position switch, the person who programmed your radio may have decided that the 2-position concentric switch would be used for programming your scan list. If you're lucky, then your radio has an LCD display. If so, then select PROG and look for a blinking square symbol to tell you when to program your scan list and look for a letter Z with an arrow on it to tell you that your radio is scanning. On the other hand, the person who programmed your radio with a computer may have decided that you did not need to have and of these options enabled.
