Adjusting Bias and Recording
Level Calibration
Automatically (TC-RE340 only)
Since there are many different types of cassettes on the
market, your tape deck automatically sets the
appropriate equalization characteristics and bias
current for each tape type (ATS: Automatic Tape
Selection). However, you can get better recording
results by doing the automatic bias current and the
recording level calibration.

1 Insert the cassette you want to record on.
Make sure the record-protect tabs on the cassette
have not been removed.
2 Press AUTO CAL until “CAL” appears in the
display.
Note
If the record-protect tab for that side has been removed
(see page 14), “AUTO CAL” in the display flashes three
times and automatic calibration cannot be performed.
3 Press PAUSE P to start the automatic calibration
procedure.
The automatic calibration procedure starts (i.e.,
recording test tones, rewinding, and playing
back).
During the calibration, the counter changes from
9 to 0.

When the automatic calibration procedure ends,
the tape rewinds to the original position, the
counter returns to normal and the tape deck
stops.

To cancel the automatic calibration function
Press p.
If “AUTO CAL” flashes continuously
The automatic calibration procedure has been
interrupted by:
— The end of the tape. Turn the cassette over or
rewind the tape to a new position that allows
recording of the test tone.
— Damaged tape or dirty heads. Change the cassette
or clean and demagnetize the heads (see page 14).
Updating the calibration setting
As long as the tape deck stays on, calibration data are
saved and called up each time you insert a cassette of
the same type (I, II or IV). “AUTO CAL” appears in
the display when you insert a cassette to indicate that
calibration data for that tape type exists. However, we
recommend that you repeat the automatic calibraion
procedure each time you insert a new cassette since
cassettes of the same type also vary in their
characteristics. Before recalibrating, be sure to clear the
existing calibration data by pressing AUTO CAL until
“AUTO CAL” disappears from the display. Then start
from Step 2 of the automatic calibration procedure.
