Functional Description
These keys are used to increment/decrement receive frequency while frequency is displayed and,
in combination with DISP key, to adjust timer while time is displayed.
(1) During frequency display
Each time SHIFT key is pressed, manual tuning function and auto tuning function are
alternately selected.
When auto tuning function is selected (not in shift mode), “AUTO” on LCD panel lights.
When this key is pressed while auto tuning function is selected and while time or PS is displayed,
frequency is displayed.
If no station is assigned to frequency at which seek operation has been stopped, frequency (last
channel) at which seek operation was started is displayed again. Even if mode is changed
between tape/CD and radio modes during seek operation, seek operation continues. If mode is
changed between radio mode to tape/CD mode at this time, tape/CD is displayed for about 3
seconds. If seek operation still continues after that, frequency is displayed.
When auto tuning of FM band is performed, frequency is incremented/decremented in 100 kHz
units. In manual tuning mode, it is incremented/decremented in 50 kHz units.
SEEK/MAN UP
SEEK/MAN DOWN
q Normal mode
Frequency is incremented ( SEEK/MAN UP key) or decremented ( SEEK/MAN DOWN key) 1 channel space
at a time, and presence/absence of broadcasting station (SD + IF count or SD: depending on IF/
SD switch of initial setting diode) is detected for each receive frequency.
If presence of station is detected, frequency of station is held.
q RDS seek in FM band
When presence of station is detected, RDS pin (pin 10) is checked. If RDS signal is input within
about 500 ms, input of RDS data is started. When RDS data has been input, its frequency is held.
If RDS data is not input within about 1.5 seconds, seek operation continues.
If RDS signal is missing, seek operation continues.
q PTY seek in FM band
When presence of broadcasting station is detected, whether it is an RDS station is judged.
If RDS data is input, its PTY is checked. If PTY is different from that expected, seek operation
continues. If PTY matches, its frequency is held.
q TP/SK seek in FM band
When presence of station is detected, whether it is an RDS station is judged.
When RDS data is input, TP bit is checked. If traffic information station is being received, its
frequency is held. If station is not traffic information station, seek operation continues.
If RDS signal is missing, SK pin is checked. If SK signal is present, its frequency is held. If not,
seek operation continues.
