For the keys that can be used, see the diode matrix. For a description of each key
operation, see the
AMS
,

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 Band2 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 determined by the presence of an IF count, SD signal, and SK signal), autotuning starts from
VF
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
VF
key for the first time. Autotuning is not performed automatically even if
another tuning key (other than autotuning) is pressed.

Function
To reset the VF band, press the
key or
VF
BAND
key.
The VF band has 6 independent memories. The last channel is also independent.
When the device is set to the tape or CD mode by TPSET or CDSET switch while on the VF
band, it switches to the DK standby mode. The device also switches to the DK standby mode
when the
VF
key is pressed in the tape or CD mode. In the DK standby mode,
all the keys, other than the
VF
BAND
key, are valid. When the DK switch is set to ON
in the DK standby mode, the device switches to the DK ON mode. In the DK ON mode, radio
muting (RDMUTE pin) is turned off and audio muting (AMUTE pin) is turned on.
When both the SD and SK signals or one of signals are lost during VF band reception
(including TAPE or CD DK standby mode), BEEP is output.
The SD and SK signals are checked 512 times once every 30 ms and if there are no SD and
SK signals for 256 times or more, BEEP is output.
For BEEP, 120 ms ON and 120 ms OFF are output 5 times, respectively.
Preset memory scan and auto store memory key.
The auto store memory function is enabled when initialize diode DISAMEMO is 0.
When the auto store memory is used (DISAMEMO = 0), when this key is pressed and
released within 2 seconds, preset memory scanning is performed. When this key is held
down for more than 2 seconds, operation switches to auto store memory operation.
When the auto store memory is not used (DISAMEMO = 1), the preset memory scanning
operation starts the moment the button is pressed.
The preset memory scan and auto store memory operations are described below.
(1) Preset memory scan operation
The preset memory contents are called automatically every 5 seconds.
If other than the current preset memory is being received, the preset memories are
PSCAN

called from M1, and if a present memory is being received, the preset memories are called
from the next preset memory (for instance, from M4 if M3 is being received) sequentially
every 5 seconds. This operation is shown below.

When the next preset memory is called at the end of 5 second hold, BEEP is output.
During 5-second hold, the preset memory number display flashes at 1 Hz (duty 50 %). The
“ch” display does not flash.
To stop at that preset memory during 5-second hold, press this key again, or press the
same preset memory key as the preset memory being received. Writing of preset memory
(for example, writing to M5 during M1 hold) is also possible, but the preset memory scan
operation ends when the preset memory was written.
The preset memory write operation during 5 second hold is described below.
Description

preset memory channel is called and auto preset scanning continues.
If

writable mode is canceled and the next channel is called 5 seconds after the key was pressed.

(2) Auto store memory
This operation searches for a broadcast station and writes it to preset memory automatically.
Broadcast station search is performed in the up direction, starting from the frequency
currently being received.
If the preset memory channel which is written is receiving the current preset memory, it
is incremented from the preset memory channel being received (from M3 if M3 is being
received). If a channel other than a preset memory channel is being received, the preset
memory channel which is written is incremented from M1. When broadcast stations are

The auto store memory operation broadcast station search method in the LOCAL mode
and DX mode differs as shown below.
• DX mode

being received, and ends when the preset memories are written up to M6 or all the search
frequencies were searched once.

Description
Indicates that the device is on the VF band.
Indicates that the SK signal is input.
It lights when the SK switch is turned on at the FM and VF bands.
Indicates that a STEREO signal is input.
ST
It lights when the ST pin (pin 64) becomes Low on the FM and VF bands.
However, it does not light in the MONO mode.
Indicates that the device is in the MONORAL mode.
When the
MONO
MONO
key is pressed on the FM and VF bands, the display is inverted.
High level is output from the MONO/NR2 pin (pin 18) while this display is lit.
It is invalid on the MW and LW bands.
Indicates that the device is in the LOCAL mode.
When AUTOLOC = 0, when the
LOC
LOC
key is pressed in a radio mode (FM, MW, LW
bands), the display is inverted.
When AUTOLOC = 1, this display lights during autotuning local search.
High level is output from the LOC pin (pin 10) during autotuning while this display is lit.
Indicates that the device is in the LOUDNESS state.
When the
LOUD
LOUD
key is pressed in the radio, tape, or CD mode, this display is
inverted.
High level is output from the LOUD pin (pin 19) while this display is lit.
Indicates that the device is in the METAL state.
MTL
When the
METAL
function key is pressed in the tape mode, this display is inverted.
High level is output from the MTL pin (pin 21) while this display is lit.
Indicates that the device is in the NR1 (Noise Reduction) state.
When the device is placed into the NR1 state by
NR1
NR
function key in the tape mode,
this display lights.
High level is output from the NR1 pin (pin 22) while this display is lit.
Indicates that the device is in the NR2 (Noise Reduction) state.
The NR2 function can be used with the initialize diode ENNR2 switch.
NR2
When the device was placed into the NR2 state by
NR
function key in the tape
mode, this display lights.
High level is output from the MONO/NR2 pin (pin 18) while this display is lit.
DKSTBY
Lights in the DK standby and DK ON modes in the tape/CD mode.
Indicates the direction of tape travel.
In the tape mode, this display indicates the tape direction according to the state of the RL
switch. If the FF switch is ON, this display flashes. For more information, see the description
of each pin.
