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.

AF When pressed short, AF/REG switching mode is selected.
When AF/REG switching mode is selected, the radio checks the signal strength of the AF all the
time. When pressed long, it is activated as regional mode ON/OFF.
– Regional mode ON:
AF switching or PI SEEK is implemented to the station which have all PI codes same as current
station. REG segment is turned on, in LCD display.
– Regional mode OFF:
The regional code in the format of PI code is ignored when AF switching or PI SEEK is implemented.
PTY While selecting PTY type, its selection is implemented by preset buttons as described in
preset key. When PTY is selected, the radio starts to search corresponding PTY information, and
stops if the corresponding PTY information is detected.
When PTY mode is selected, the PTY switch is shared as follows:
PTY music group ---- PTY speech group ---- OFF
MUSIC SPEECH
1. POP M, ROCK M 1. NEWS, AFFAIRS, INFO
2. EASY M, LIGHT M 2. SPORT, EDUCATE, DRAMA
3. CLASSICS, OTHER M 3. CULTURE, SCIENCE, VARIED
4. JAZZ, COUNTRY 4. WEATHER, FINANCE, CHILDREN
5. NATION M, OLDIES 5. SOCIAL, RELIGION, PHONE IN

TA When pressed short, it is activated as TA mode on or off
When TA mode is on and traffic announcement is transmitted
– When the unit is it CD/MP3 mode, it will switch to radiomode temporarily.

TA SEEK/TA ALARM MODE When press AUDIO button for more than 2 seconds, it is activated
as selecting mode of these function.
TA SEEK Mode or TA ALARM mode is selected by rotary VOL left or right.

When newly turned station does not receive TP information for 5 sec., the radio retunes to next
station which has not the same station (PI) as the last station, but has the TP information.
In TA seek mode, the current station can be changed to the completely different station because
the unit searches TP station when the field strength of the current station is very weak, or the
current station has no TP signal.
- TA ALARM mode:
Any automatic retune mode is not activated, just can hear Beep sound.
MASK DPI MODE When press AUDIO button for more than 2 seconds, it is activated as selecting
mode of these function.
MASK DPI: masked only the AF which has different PI.
MASK ALL: masked the AF which has different PI and NO RDS signal with field strength.
RETUNE L / S MODE When press AUDIO button for more than 2 seconds, it is activated as
selecting Retune mode.
RETUNE L: Select 90 seconds as the initial time of automatic TA search.
RETUNE S: Select 30 seconds as initial time.
