@ FM muting off/scan level selector (muting)
This selector is used when releasing the FM broadcast
muting function and when setting the scan level for FM
broadcasts.
¢ Releasing the muting function (off)
In mountainous areas, etc., where broadcast waves are
weak, breakup in the sound can be lessened by lightly
pressing the button. When this is done, the function is
released only for the statin being received.
However, when a tuning button is pressed to begin
scanning, the former scan level will be used.
© Setting the scan level (scan level)
This level setting is effective only for the automatic preset
memory and auto tuning.
When the button is held down, "dB" will be displayed and
the numbers 30, 40, and 50 will be displayed in order.
When the desired level is reached, release the button.
The higher the level, the more noise is reduced. Stations
with good reception can use " a high level", but stations
below the set level cannot be received.
In order to receive these station, the level has to be reset.

FM:
Press this button to listen to an FM broadcast.
+25 kHz:
The displayed FM frequency can be shifted by +0.025 MHz
(+25 kHz) in order to precisely align with the frequency of
the FM broadcast station.
lf the FM button is pressed until the final digit of the
frequency display is a small "5", the FM frequency will shift
+0.025 MHz (+25 kHz).
To return to the original indication, press until the final small
"5" digit disappears.
AM:
Press this button to listen to an AM broadcast.
allocation:
A frequency step of either AM 9 kHz or AM 10 kHz can be
selected. Set to the appropriate position for your locality.
When the AM button is pressed slightly longer and then
released when the AL10" indication illuminates, the AM
frequency "step" will change to 10 kHz.
To return to the original 9 kHz, press the AM button slightly
longer, and then release it when the "AL9" indication
illuminates.
© Recording-level check button (rec level)
This button is to be used for adjustment of the recording
level when recording an FM broadcast.
When this button is pressed, the microcomputer functions to
emit a reference signal of precisely 333 Hz from the output
terminals of this unit. The word "CAL" (calibration) and then,
soon thereafter, "0.33 kHz" will be shown by the digital
display.
Adjustment of the recording level
Use the input-level control(s) of the tape deck to make the
adjustment while watching the recording-level meters.
e For VU meters and level meters:
Adjust so that the indication is about +2 VU or +2 dB.
e For peak-level meters:
Adjust so that the indication is about —2 dB.
Notes:
1) Because the ideal recording level is apt to vary depending
upon the program source and the characteristics of the
tape deck, the adjustment should be made by also
considering those factors.
2) Don't press the operation buttons of this unit during a
recording. If they are pressed, the recorded soundmay be
disturbed.
