Pressing the TUNE/SEEK button to the first detent manually tunes the radio to a higher or lower radio station. Holding the button at the first detent for a few seconds continues tuning the radio until the button is released. Pressing the TUN E/SEEK button to the second detect and then releasing the button causes the radio to seek to the next higher or lower radio station.
