m In the Preset Stations window, type in the frequency of the
station you want assigned to that row.
Note: If you just type the station’s call letters (usually four
capital letters) and not the frequency, the station won’t be
assigned as a preset station. You must type in the frequency
because the frequency is what the FM tuner uses to find the
station.
You can also type in the station’s call letters and your own
description, although they’re not required. To display this
information on the Preset Station buttons, see “Labeling
Preset Station Buttons” later in this section.
3 Click on the pop-up menu (the arrow next to the current
station’s frequency in the FM Radio window) to see the list
of all stations you have preset. You can use this menu to
choose a preset station to listen to.
If you want to make changes to the Preset Station buttons,
see “Changing Preset Stations” later in this section.
