Description of Functions
This key selects AF operation mode.
It is valid only when the FM band is been received.
If this key is pressed, the “RDS” display on the LCD panel lights thus placing the device
in AF operation enable mode.
While the “RDS” display is on, when the AF operation start condition is met, AF operations
performed.
If AUTO SEEK is performed by the SEEKUP / SEEKDOWN key in this mode, it
results in operation of RDS broadcasting station detection.
If the key is pressed again while the “RDS” display is lit, the “RDS” display is extinguished,
thus placing the device in the AF operation disable mode.
If an RDS broadcasting station is being received, incorporation of RDS data is performed
regardless of the ON/OFF state of the “RDS” display.
This key selects traffic information interrupt operation mode.
When this key is pressed, the “TP/SK” display on the LCD panel is lit placing the device in
traffic information stand-by status.
If both RDS TP and TA bits become 1 at this time, the device is placed in the traffic information
interrupt status, thus displaying “
” on the 14 segments of the LCD panel and
switching the sound to RADIO mode.
If the TP/TA bit becomes other than 1 during the traffic information interrupt, the traffic informa-
tion stand-by mode is restored and the sound before the traffic information interrupt is returned.
If the key is pressed again while the “TP/SK” display is lit, the “TP/SK” display is
extinguished and the traffic information stand-by status is canceled.
If the device is in the midst of a traffic information interrupt at this time, the traffic infor-
mation interrupt is canceled and the sound before the traffic information interrupt is returned.
While “TP/SK” remains unlit, no traffic information interrupt is accepted. The SEEK operation
while the “TP/SK” display is lit is for searching traffic information stations only.
