Sony HT-SF1300 User Manual

This receiver also allows you to use RDS 
(Radio Data System), which enables radio 
stations to send additional information along 
with the regular program signal. You can 
display RDS information.

• RDS is operable only for FM stations.
• Not all FM stations provide RDS service, nor do 

they provide the same type of services. If you are 
not familiar with the RDS services in your area, 
check with your local radio stations for details.

Simply select a station on the FM 
band using direct tuning (page 48), 
automatic tuning (page 47), or 
preset tuning (page 49).

When you tune in a station that provides RDS 
services, “RDS” lights up and the program 
service name appears on the display.

RDS may not work properly if the station you tuned 
to is not transmitting the RDS signal properly or if 
the signal strength is weak.

Each time you press the button, RDS 
information on the display changes cyclically 
as follows:
Program Service name 

t Frequency t 

Program Type indication

a)

 

t Radio Text 

indication

b)

 

t Current Time indication (in 

24-hour system mode) 

t Sound field 

currently applied 

t Volume level

a)

b)

Text messages sent by the RDS station.

• If there is an emergency announcement by 

government authorities, “ALARM” flashes in the 
display.

• When the message consists of 9 characters or more, 

the message scrolls across the display.

• If a station does not provide a particular RDS 

service, “NO XXXX” (such as “NO TEXT”) 
appears on the display.
