Receiving RDS radio stations Ç

RDS (Radio Data System) is a broadcasting
service that allows FM stations to send additional
information along with the regular FM radio
signal.

This additional information can contain:

• STATION NAME : The station name is
displayed.

• PROGRAM TYPE (PTY): The following
program types exist and can be received by
your tuner: News, Affairs, Info, Sport,
Educate, Drama, Culture, Science, Varied,
Pop M, Rock M, M.O.R. (middle of the road
music), Light M, Classics, Other M.

• RADIO TEXT (RT) : Text messages appear in
the display.

• FREQUENCY : The frequency of the station is
displayed.

When you have tuned to an RDS station, the
RDS logo (

Ç) and the station name will appear

on the display:

• The display normally shows the radio station
name if available.
By repeatedly pressing RDS (or RDS/CD TIME
on the remote control) you can change the
type of display information:
– The display shows in turn: STATION NAME

-> PROGRAM TYPE -> RADIO TEXT ->
FREQUENCY -> STATION NAME ...

Notes :
1 When you press RDS (or RDS/CD TIME on

the remote control) and the display shows
“NO PS”, it indicates that either the tuned
station is not transmitting RDS signal or it is a
non RDS station.

2 When no program type is transmitted by the

radio station, the display shows “NO PTY”.

RDS Search

RDS allows you to select memorized FM stations
according to programme type. More and more
stations are codifying their programme type
allowing efficient

search with the SEARCH

function. The transmitted code

is, however, the

responsibility of the radio station.

• By using the SEARCH button on the system or
on the remote control, you can call up the
programme types one after another.

• Press S or T to start scanning the
memorized stations in forward or backward
direction to find a station broadcasting the
required programme type. As soon as such a
station is found it is tuned to.

RDS Clock

Some RDS station may be transmitting a real time
clock at an interval of every minute.

• If the clock time has not been set manually by
you (e.g. ‘0:00’ is flashing); the current RDS
clock time will be stored automatically when
the RDS station transmits the real time clock.

• If you have already set the clock time, the set
time will not be replaced when the RDS clock
time is being received
