Simple scan
For a simple scan, you specify a starting channel (MIN CHAN) and an ending channel
(MAX CHAN) for the scan. These settings determine the number of channels in the scan.
For example, if you set MIN CHAN to 101 and MAX CHAN to 110, there will be 10
channels in the scan list.
The starting channel number must be lower than the ending channel number. If you enter
an invalid value, the message "TOO SMALL" or "TOO LARGE" will be displayed
briefly. The displayed channel number will default to the lowest available channel (i.e.,
101) or the highest available channel (i.e., 240).
