5.2.2 PS (Program Service Name)
This data is used for the PS display.
The PS display is made once when the same PS data is input two or more times.
The PS display appears about 5 seconds after the tuning operation is completed. If the PS data cannot be received
during about 5 seconds, the PS display appears when the PS data is eventually received.
Once PS data has been received, if the display is changed by the
DISP key or the TP/SK mode ON/
OFF change is performed even if no PS data can be received thereafter, the last PS data is stored, and 3 seconds
after displaying frequency, the stored PS data is displayed.
5.2.3 PTY (Program Type)
Used for alarm identification. When the alarm is received, the device is switched over to RADIO mode if in TAPE/
CD mode.
At this time, the LCD panel displays “
”.
5.2.4 AF (Alternative Frequency)
Used as a switchover frequency list.
(1) AF list input
The AF function can be used for both METHOD A and METHOD B. Up to 25 lists can be input. If AF’s
header block is received, the AF pointer is reset to the front and the lists are stored in the order of their
transmission. If more than 25 AF lists are sent, data is overwritten starting from the top of the lists.
If, in METHOD B, blocks for the same frequency arrive one after another, they are linked together to
form a single AF list. Even when lists are sent in pairs of a descending sequence, all the AF lists are
input.
The method of input for AF lists is shown in Figure 5-3 Flow of AF List Input.
