programs such as sports or music. 
You can receive the following types of Radio Data 
System signals. 
PS (Program Service): 
Shows commonly known radio station names. 
PTY (Program Type): 
Shows types of broadcasted programs. 
RT (Radio Text): 
Shows text messages sent by the radio station.

NOTE
• Radio Data System may not work correctly if the 
radio station is not transmitting the signals prop-
erly or if the signal is weak.
