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 4-7 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.
