You have to enter each channel into the scan list then it will scan.
Look for SCH on the number pad label. Choose the channel you want to
scan, you will need more than one, and while pressing Function, press
SCH to add that channel to the scan list.
As you press the Function / SCH you will see little channel numbers
appear across the top of the radio. This is the indication the channel
is included in the scan list. Just press Function/SCH until the
channel you have on the display appear in that list across the top of
the display.
