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.
"PTYI" (Dynamic PTY Indicator) will appear whilst the Dynamic PTY station is
received.
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 follows:
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:

Notes for RDS operation
If any of the following events occur, it does not mean that the unit is faulty:
"PS", "NO PS" and a station name appear alternately, and the unit does not oper-
ate properly.
If a particular station is not broadcasting properly or a station is conducting tests,
the RDS reception function may not work properly.
When you receive an RDS station whose signal it too weak, information like the
station name may not be displayed.
"NO PS", "NO PTY" or "NO RT" will flash for about 5 seconds, and then the fre-
quency will be displayed.

Notes for radio text:
The first 8 characters of the radio text will appear for 4 seconds and then they will
scroll across the display.
If you tune in to an RDS station which is not broadcasting any radio text, "NO RT"
will be displayed when you switch to the radio text position.

Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.

Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression “capacitance/withstand
voltage” is used.
