7.3 Seek Up/down
The operation is started when the
SEEK/MAN UP
/
SEEK DOWN
key is pressed in a mode other than shift mode
in tuner mode.
If the SD level and initial setting diodes AM SD/IF and FM SD/IF are ON, the IF count is checked. When
conditions for presence of a station are satisfied two times at intervals of 500 ms, the seek operation ends.
In the RDS mode and TP/SK mode, an RDS station and traffic information station are detected by
operation shown in the timing chart below, after the above condition has been satisfied.
(1) Normal mode
1 : Key ON chattering prevention
2 : Leading mute
3 : Division ratio setting
4 : PLL lock wait
5 : SD stabilization wait 1
6 : SD stabilization wait 2
7 : Trailing mute
