The lowest frequency of each area is M1 to M6 of the FM2, FM3, VF, and MW2 bands of other
than Europe 1 and 2.
Tape mode
These keys can be used as tape function keys by means of initialize diode matrix switches
ENTPK, KAMS, and KMTL.
For the keys that can be used, see the diode matrix. For a description of each key
operation, see the

key items.
VF (traffic information) broadcast station search key. Its operation is described below.
When this key is pressed in the radio mode (FM, MW, or LW band), the LCD panel “VF”
display and Band
2
pin output are inverted.
When this key is pressed, the VF band is selected and 375 to 500 ms later, whether or not
there is a broadcast station (IF count and SD check) and SK signal are detected. If no VF
broadcast station is judged not to be present (The presence of a VF broadcast station is de-
termined by the presence of an IF count, SD signal, and SK signal), autotuning starts from
that frequency.
When the first broadcast station is detected, that frequency is held until the autotuning key
is pressed thereafter, even when there is no SK signal.
When the IF count and SD check are judged to be present, the autotuning operation is the
same as normal autotuning, except that the SK signal is detected after 375 to 500 ms.
Autotuning (seek up) is performed automatically only when the VF band is selected by
key for the first time. Autotuning is not performed automatically even if
another tuning key (other than autotuning) is pressed.
