RECORDING SETTING USING RECORDING CALIBRATION
FUNCTION
1 Insert a cassette tape for recording.
When not recording from the beginning of a tape, set to the
desired position.
2 Press the CALIBRATION ON/OFF button and
set recording calibration to ON.
The level meter display changes to calibration.
This cassette deck has a function whereby bias and level can be
adjusted independently. This allows correction for dispersion of
characteristics affected by the cassette tape, resulting in better
recording quality.

CALIBRATION BIAS control knob
Turning clockwise (+) increases bias. The limit of high-pass
range will be decreased, but distortion will be decreased.
Turning counterclockwise (—) decreases bias. Although
distortion will be increased, the limit of high-pass range will be
increased.
By utilizing these characteristics, sound quality can be changed
according to the cassette tape or recording source.

REC CALIBRATION
Although the auto tape selector of this cassette deck
automatically sets the characteristics optimum to the tape in use,
a slight difference remains depending on tape brands. The rec
CALIBRATION function allows you to correct such a difference
and set the characteristics optimum to the particular tape.
Greater effect can be obtained by using this function every time
you record.
NOTES:
¢ Playback or fast forward do not function during rec
CALIBRATION mode. The cassette tape will stop when the rec
CALIBRATION. ON/OFF button is turned ON _ during
playback/recording.
B Press the CALIBRATION ON/OFF button
again.
Recording stops, and calibration display will return to level meter
display.
6 Rewind the tape to the starting position.
Press the Rewind button (~@@) and reverse the tape to the
starting position of recording.
CALIBRATION LEVEL contro! knob
Adjusts the recording level according to the recording sensitivity
of the cassette tape. Turning clockwise (+) increases the
recording level, and turning counterclockwise (~~) decreases the
level.
This function is especially useful for recording using the DOLBY
NR system.
How REC CALIBRATION works:
When the rec CALIBRATION ON/OFF button is pressed, a built-in
oscillation circuit is activated and measurement signals will be
recorded onto the cassette tape. An adjustment dependent on
the tape will be completed by monitoring the signals and
adjusting the level to a certain standard. These signals will be
erased when the tape is rewound and rerecording is made.
This setting is valid during recording only. There is no need to use
it for playback.
° Metal tapes might not be adjusted to optimum value, because
their high-pass frequency does not change much when the
bias is changed.
