EON (Enhanced Other Network) system (for traffic announcement function)
If the RDS station (with EON data) you are listening to is not broadcasting a
traffic information program and the audio system is in the TA (Traffic
announcement) mode, the radio will be switched automatically to a station
broadcasting a traffic information program in the EON AF list when traffic
information begins.
When listening to a disc
When the traffic information program starts, the disc playback mode is inter-
rupted and the traffic information is automatically broadcasted. When the
program ends, the initial operation resumes.
When the 12-volt battery is disconnected
All preset stations are erased.
Reception sensitivity
Maintaining perfect radio reception at all times is difficult due to the contin-
ually changing position of the antenna, differences in signal strength and
surrounding objects, such as trains, transmitters, etc.
The radio antenna is mounted inside the rear window. To maintain clear
radio reception, do not attach metallic window tinting or other metallic
objects to the antenna wire mounted inside the rear window.
About Time shift
The times at which playback is possible depend on the bit rate of the DAB
station to be recorded, the amount of DAB unit memory, and the time at
which reception of the broadcast began.
