available in the control head, and when editing, the SELECT slew switch (+/-) will bring
up only valid choices for each type of code. Pressing HELP while editing these
positions of the channel data will bring up the tone table for reference. The Frequency
shown will have the decimal fraction truncated when displayed on the control head.
