The FM band can be configured to seek or scan for particular types of radio programming (such as news, sports or classical music). When categories are selected, the radio only seeks or scans for the stations that are broadcasting programs with the selected category codes. Not all stations broadcast these codes. When categories are selected, the FM band displays CATEGORIES with a filter symbol as shown in Figure 1.
Categories are also known as program types (PTYs).
