RDS

Overview of the RDS function

Radio Data System (RDS) is a broadcasting service that allows FM stations to send additional digital information along with the regular radio programme signal. Your car stereo offers you a variety of services. Here are just a few: retuning the same programme automatically, listening to traffic announcements, and locating a station by programme type.

Notes

•Depending on the country or region, not all of the RDS functions are available.

•RDS may not work properly if the signal strength is weak or if the station you are tuned to is not transmitting RDS data.

Displaying the station name

The name of the current station lights up in the display.

Select an FM station (page 9).

When you tune in an FM station that transmits RDS data, the station name appears in the display.

Note

The “*” indication means that an RDS station is being received.

Changing the displayed item

Each time you press (DSPL), the item changes as follows:

Frequency (Station Name) ÷Clock

After you select the desired item, the display will automatically change to the Motion Display mode after a few seconds.

In the Motion Display mode, all the above items are scrolled in the display one by one in order.

continue to next page n

11

Tip

The Motion Display mode can be turned off. (See ”Changing the sound and display settings” on page 19).

Note

“NO NAME” appears if the received station does not transmit RDS data.

Retuning the same programme automatically

— Alternative Frequencies (AF)

The Alternative Frequencies (AF) function automatically selects and retunes the station with the strongest signal in a network. By using this function, you can continuously listen to the same programme during a longdistance drive without having to retune the station manually.

Frequencies change automatically.

98.5MHz	96.0MHz

Station 102.5MHz

1 Select an FM station (page 9).

2 Press (AF/TA) repeatedly until “AF-ON” appears.

The unit starts searching for an alternative station with a stronger signal in the same network.

Note

When there is no alternative station in the area and you do not need to search for an alternative station, turn the AF function off by pressing (AF/TA) repeatedly until “AF TA-OFF” appears.

Changing the displayed item

Each time you press (AF/TA), the item changes as follows:

	Ó TA-ON		Ó AF TA-ON*
	AF-ON Ò		AF TA-OFF Ò

*Select this to turn on both the AF and TA functions.

Notes

•When “NO AF” and the station name flash alternately, it means that the unit cannot find an alternative station in the network.

•If the station name starts flashing after selecting a station with the AF function on, this indicates that no alternative frequency is available. Push the SEEK/AMS control up or down while the station name is flashing (within eight seconds). The unit starts searching for another frequency with the same PI (Programme Identification) data (“PI SEEK” appears and no sound is heard). If the unit cannot find another frequency, “NO PI” appears, and the unit returns to the previously selected frequency.

Listening to a regional programme

The “REG-ON” (regional on) function lets you stay tuned to a regional programme without being switched to another regional station. (Note that you must turn the AF function on.) The unit is factory preset to “REG-ON,” but if you want to turn off the function, do the following.

1 During radio reception, press (SHIFT), then press (3) (PLAY MODE) repeatedly until “REG” appears.

2 Press (4) (n) repeatedly until “REG-OFF” appears.

3 Press (SHIFT).

Note that selecting “REG-OFF” might cause the unit to switch to another regional station within the same network.

To return to regional on, select “REG-ON” in step 2 above.

Note

This function does not work in the United Kingdom and in some other areas.

12

Local link function (United Kingdom only)

The Local Link function lets you select other local stations in the area, even if they are not stored on your number buttons.

1 Press a number button that has a local station stored on it.

2 Within five seconds, press the number button of the local station again.

3 Repeat this procedure until the desired local station is received.

Listening to traffic announcements

The Traffic Announcement (TA) and Traffic Programme (TP) data let you automatically tune in an FM station that is broadcasting traffic announcements even if you are listening to other programme sources.

Press (AF/TA) repeatedly until “TA-ON” or “AF TA-ON” appears.

The unit starts searching for traffic information stations. “TP” appears in the display when the unit finds a station broadcasting traffic announcements. When the traffic announcement starts, “TA” flashes. The flashing stops when the traffic announcement is over.

Tip

If the traffic announcement starts while you are listening to another programme source, the unit automatically switches to the announcement and goes back to the original source when the announcement is over.

Notes

•“NO TP” flashes for five seconds if the received station does not broadcast traffic announcements. Then, the unit starts searching for a station that broadcasts it.

•When “EON” appears with “TP” in the display, the current station makes use of broadcast traffic announcement of other stations in the same network.

13

To cancel the current traffic announcement

Press (AF/TA) or (SOURCE).

To cancel all traffic announcements, turn off the function by pressing (AF/TA) until “AFÊ TA-OFF” appears.

Presetting the volume of traffic announcements

You can preset the volume level of the traffic announcements beforehand so you won’t miss the announcement. When a traffic announcement starts, the volume will be automatically adjusted to the preset level.

1 Select the desired volume level.

2 Press (AF/TA) for two seconds.

“TA” appears and the setting is stored.

Receiving emergency announcements

If an emergency announcement comes in while you are listening to the radio, the programme will be automatically switched to it. If you are listening to a source other than the radio, the emergency announcements will be heard if you set AF or TA to on. The unit will then automatically switch to these announcements no matter which source you are listening to at the time.

Presetting the RDS stations with the AF and TA data

When you preset RDS stations, the unit stores each station’s data as well as its frequency, so you don’t have to turn on the AF or TA function every time you tune in the preset station. You can select a different setting (AF, TA, or both) for individual preset stations, or the same setting for all preset stations.

Presetting the same setting for all preset stations

1 Select an FM band (page 9).

2 Press (AF/TA) repeatedly to select either

“AF-ON”, “TA-ON” or “AF TA-ON” (for both AF and TA functions).

Note that selecting “AF TA-OFF” stores not only RDS stations, but also non-RDS stations.

3 Press (SHIFT), then press (3) (PLAY

MODE) repeatedly until “BTM” appears.

4 Press (4) (n) until ”B.T.M” flashes.

5 Press (SHIFT).

Presetting different settings for each preset station

1 Select an FM band, and tune in the desired station (page 10).

2 Press (AF/TA) repeatedly to select either

“AF-ON”, “TA-ON” or “AF TA-ON” (for both AF and TA functions).

3 Press the desired number button until “MEM” appears.

Repeat from step 1 to preset other stations.

Tip

If you want to change the preset AF and/or TA setting after you tune in the preset station, you can do so by turning the AF or TA function on or off.
