Adjusting Bias and Recording
Level Calibration
Automatically
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.

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

Press p on the deck you’re using.
If “A” or “B” flashes continuously
The automatic calibration procedure has been
interrupted by:
• The end of the tape. Reverse the tape direction 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 19).
Updating the calibration setting
If you insert a cassette and “[A] CAL” or “CAL [B]”
appears in the display, it means that automatic
calibration data in that deck for that tape type (I, II or
IV) exists. However, we recommend that you repeat
the automatic calibration procedure each time you
insert a new cassette since cassettes of the same type
also vary in their characteristics.
Before recalibrating, be sure to turn off “[A] CAL” or
“CAL [B]” by pressing the DECK A or DECK B button.
Then start from Step 2 of the automatic calibration
procedure.
