When emergency broadcasting is started, radio mode is selected, and the emergency broadcast is received. This
• PI seek is performed if best station has failed in RDS mode.

• PI seek is terminated if all the following conditions are satisfied.
• If an RDS station having the same PI code is not found after the band has been subject to one round of
• PTY seek is performed when seek is performed in PTY mode.
• Only an RDS station from which the same PTY code as PTY displayed before the start of PTY seek is selected
• PTY seek is completed if all the following conditions are satisfied.
• If an RDS station having the same PI code is not found after the band has been subject to one round of
• TP/SK seek is performed if seek is performed in TP/SK mode.
• Only an RDS station from which TP = 1 is read is selected from all the stations that are judged to have a station.
• TP/SK seek is terminated if all the following conditions are satisfied.
• If RDS mode is off, however, the station for which the SK pin (pin 65) is low is also selected.
