USING THE RDS FUNCTION

What is RDS?

The RDS (Radio Data System) is a digital information system developed by the EBU (European Broadcast Union). Piggy-backed on normal FM broadcasts, RDS offers a variety of

information services and automatic retuning functions for RDS-compatible car stereos. In 1988, RDS became available in the United Kingdom, France, West Germany, Ireland and Sweden. Test transmissions are being conducted in many other european countries. It is expected that RDS will be available in most western european countries in the near future.

When AF ON is selected and the state of AF switching mode is displayed by AF symbol in the display.

AF switching mode off.

AF switching mode on, and has RDS information.

AF flashing: switching mode on, but RDS information is not received yet.

When AF switching mode is selected, the radio checks the signal strength of AF all the time.

The interval of checking time of each AFs depends on the signal strength of current station, from a few minute for strong station to a few seconds for weak station. Every time that new AF is stronger than current station, it switches over to that frequency for very short time, and NEW FREQUENCY is displayed for 1-2 second. Because the mute time of AF switching Or checking time is very short, it is almost inaudible in case of normal program.

When TA mode is on (TP is displayed on LCD), it will begin to seek TA station.

2) Temporarily switch over to an EON linked station when EON detects a traffic announcement on that other program, and TP will be displayed on LCD

3) If volume level is below 20, volume level is raised to 20, and returns to its previous mode and volume level when the traffic announcement is over. If volume is adjusted during traffic announcement, only the previous volume is valid.

3. 'PTY' function (PROGRAM TYPE)
