Using the Radio Data System (RDS)
RDS is a broadcasting service which a growing number of FM stations provide.
These FM stations send additional signals along with their regular programme
signals. They send their station names, and information about the type of pro-
gramme such as sports or music, etc.
When tuned to an RDS station, "RDS" and the station name will be displayed.
"TP" (Traffic Programme) will appear on the display when the received broadcast car-
ries traffic information, and "TA" (Traffic Announcement) will appear whilst a traffic
information is on air.
"EON" will appear whilst the EON (Enhanced Other Networks information) data is
broadcast.
"PTYI" (Dynamic PTY Indicator) will appear whilst the Dynamic PTY station is
received.
"RT" (Radio Text) will appear whilst the unit receives the Radio text data.
"CT" (Clock Time) will appear whilst the unit receives the RDS CT data.
You can control the RDS by using the buttons on the main unit only.
Information provided by RDS
Each time the DISPLAY MODE button is pressed, the display will switch as fol-
lows:
When you are tuning in to a station other than an RDS station or to an RDS station
which sends weak signal, the display will change in the following order:
Station name (PS) Frequency
Programme type (PTY) RDS clock time
(8 Languages)
Date (for 3 seconds)
Programme type (PTY) Clock-time and date (CT)
(English fixed)
Radio text (RT)

Maintenance
Dirty heads, capstans or pinch rollers can cause poor sound and tape jams. Clean these parts with a cotton swab moistened with commercial head/pinch roller cleaner or isopropyl alcohol. When cleaning the heads, pinch rollers, etc., unplug the unit which contains high voltages. After long use, the deck’s heads and capstans may be- come magnetised, causing poor sound. Demagenetise these parts once every 30 hours of playing/recording time by using a commercial tape head demagnetiser. Read the demagnetiser’s instructions carefully before use. Clean the dust or stain on the CD pickup lens using a com- mercial cleaning disc (brush type).

Notes:
1: Description of the "FM IF Adjustment" is not carried on this

has been best adjusted in the factory so that its further

FM front end assembly, no adjustment is needed either.
2: The parts in the FM front end section are prepared in a
