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.

1Insert the cassette you want to record on.

Make sure the record-protect tabs on the cassette have not been removed.

2Press AUTO CAL until “CAL” appears in the display.

Note

If the record-protect tab for that size has been removed (see page 11), “AUTO CAL” in the display flashes three times and automatic calibration cannot be performed.

3Press P PAUSE 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.

4Start the actual recording (see page 6).

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 11).

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.
