RDS may not work properly if the signal strength is weak or if the station you are tuned to is not transmitting RDS data. Note If you try to store another station on the same number button, the previously stored station will be erased. The alternative frequencies (AF) function allows the radio to always tune into the area's strongest signal for the station you are listening to. When AF function is on: this unit's factory-set setting restricts reception to a specific region, so you won't be switched to another regional station with a stronger frequency. If you leave this regional programme's reception area or would like to take advantage of the whole AF function, press (AF) for 2 seconds until "REG-OFF" appears. Note This function does not work in the United Kingdom and in some other areas. This function enables you to select other local stations in the area, even if they are not stored on your number buttons. The unit starts searching for an alternative station with a stronger signal in the same network. If "NO AF" flashes, the currently tuned into station does not have an alternative frequency. If you want to change the on/off setting while playing a CD, press (AF). When there is no alternative frequency in the area or when you do not need to search for one, turn the AF function off by selecting "AF-OFF.
