Once you have stored a PTY for each of your preset
stations, you can recall a PTY preset by touching
the preset station for less than two seconds. Then use
TUNE/SEEK or SCAN to locate a station for that
PTY selection.
ALERT: This type of announcement warns of national
or local emergencies. You will not be able to turn
off alert announcements. Alert announcements will come
on even if RDS mode is turned off. ALERT appears
on the display when an alert announcement plays.
The audio system uses TA volume during these
announcements. To increase volume, touch the VOL
button on your steering wheel or use the VOL up
and down buttons during the announcement. See "Voice
Guidance Volume Settings" under Setup Menu on
page 4-13 for more information. When an alert
announcement comes on the tuned radio station or a
related network station, you will hear it even if the
volume is muted or a CD is playing. If the audio
system tunes to a related network station for an alert
announcement, it will return to the original station when
the announcement is finished. If the CD player is
playing, the player will stop for the announcement and
resume when the announcement is finished.
