In case of exist 2 more stations having the desired (specified) “PTY” or “TI”, the receiver will select and switch to ON station
comparing field strength at the same time. But when the frequency of ON station exists in the preset-memory, then receiver
switches straight to that ON station (CH), without comparing field strength so can make a quick switching from TN—ON station.
Preset memory takes priority of switching TN—ON station.
Therefore ASPM is usefull not only for PTY search but also for rapid EON switching.
Anyway CD-BA1500H EON is basically stand-by and receiving method, along with the Guidelines for EON implementation.

1. Introduction of RDS for CD-BA1500H.
CD-BA1500H RDS function is equal to adding EON feature to the current CD-C75H RDS.
EON feature is EON—PTY and EON—TI.
Although PTY and TI indicators are separated, PTY contains TI in the PTY items (software) like current PTY search items.
EON feature is EON—PTY and EON—TI.
Although PTY and TI indicators are separated, PTY contains TI in the PTY items (software) like current PTY search items.

RDS is a broadcasting service which a growing number
of FM stations are now providing. It allows these FM
stations to send additional signals along with their regu-
lar programme signals. For example, the stations send
their station names, and information about what type of
programme they broadcast, such as sports or music,
etc.
When tuned to an FM station which provide the RDS
service, the RDS will appear, the station frequency (and
then the station name if sent) is displayed.
The TP (Traffic Programme) will appear on the display

The PTYI (Dynamic PTY Indicator) will appear whilst the
Dynamic PTY station is being received.
Note:
When the TP and TA appear at the same time, an an

nouncement is being made.
When only the TA appears, an announcement is not
being made.
