The TP (Traffic Programme) will appear on the display when the received broadcast carries traffic announcements, and
the

EON will appear whilst the EON (Enhanced Other Networks information) data is being broadcast.
The PTYI (Dynamic PTY Indicator) will appear whilst the Dynamic PTY station is being receive
d.
