RDS functions

The DT-220 equips with 4 different RDS functions:

1) CT (Clock Time):

Automatic adjustment of time.

2) PS (Program Service):

Display of station name in 8 characters .

3) TA (Traffic Announcement):

Automatic selection of traffic information with EON

(Enhanced Other Networks)

4) AF (Alternative Frequencies):

Automatic selection of relatively stronger signal

among the same station’s networks.

CT (Clock Time) – Clock auto adjustment

Besides the possibility to set the clock manually, with the help of RDS-CT function, the correct time can be set with the auto clock adjustment button.

is on and display is flashing and when the CTfunction can set the time, the will stop flashing and showing continuously until the button once again is pressed. Of course, the CT-function can work under condition that RDS signal is well received.

Therefore when is showing in the display, you know the clock time is correct adjusted at the moment.

GB

PS (Program Service)- Automatic stations name showing in 8 characters As long as a FM-station has RDS system and PS function, the station name will appear.

However when you recall a preset station, you will see first frequency a few seconds before the display shows station name.

TA (Traffic Announcement)- Automatic selection of traffic information This function searches and stands by for a traffic information using TP (Traffic Program) and TA (Traffic Announcement) data.

Using this function, the radio automatically searches the traffic information from the station you are listening to and changes its mode to receive the traffic announcement when the broadcasting starts.

11

In order to listening traffic information, just press

Traffic-info button and display car symbol appears indicating TA-function is on.

And when TP/TA is coming/activating (the traffic announcement is not continuously sending but only when it is important/meaningful traffic news, for example, traffic accident or urgent ambulance traffic on the way), the normal radio program is stopped at once and traffic announcement is coming instead

(at this time, the car symbol in the display is flashing).

And when the traffic announcement is finished

(in most case very short time of traffic information, for example some 10-20 seconds), the normal program comes back again and the car symbol stops flashing at standby mode again unless the

Traffic-info button is pressed again.

12

Notes :

* When the station you are listening to is not traffic

information station nor station with EON data, a

beep sounds.

* When the RDS data is not received continuously,

the small car symbol disappears in the display

even if the reception of a traffic information is

standing by.

* If MW (AM) band is tuned, the car symbol in the

display turns off automatically. When you tune in

FM again, the car symbol on again and TA function

is in standby.

* When the radio is off, the traffic announcement

does not work .

Therefore if you like to listen to traffic information, the

TA must be on standby mode (by pressing Trafficinfo button and car symbol appears on the display).

TA with EON– Enhanced Other Networks

The EON function extends the radio function by enabling it to track other stations transmitting the

EON data while it is tuned to a network station.

If the radio is receiving a station which is transmitting the EON data while TA- function is on, it will automatically tune to another station

(same network) when the station starts broadcasting a traffic announcement.

GB

Example:

While you are listening to the BBC-1 broadcasting when the traffic information starts at the BBC-2 station, the radio tunes to the station (BBC-2) automatically. And when the traffic announcement is over, the radio will return to the previous station.

To stop the traffic information, press Traffic-info button. The unit tunes to previous station automatically.

If the station has several frequencies, the radio will tune one by one automatically. In case that stations are preset in the preset memories by preset tuning, the radio will choose the frequencies from preset memories.

13

AF (Alternative Frequencies)- Automatic selection of relatively stronger signal

Continuously press the AF button until the station with a stronger signal is found.

Some stations such as BBC has several different frequencies. The radio begins to search for an alternative frequency with a stronger signal in the same network from the AF-data. If a stronger signal station is found, the radio re-tunes to the station.

If no alternative frequency is found, “ NO AF” appears in the display.
