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. You can do automatic calibration on either deck.

4Press PAUSE Pto 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.

5Start the actual recording (see page 4).
To cancel the automatic calibration function

Press pon the deck you’re using.

If “AUTO CAL” 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 into either deck A or B and “AUTO CAL” 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 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 turn off “AUTO CAL” in the display by pressing AUTO CAL. Then start from Step 2 of the automatic calibration procedure.

To erase calibration data on either deck A or B

The automatic calibration data is stored even if you turn off the power (Memory Backup function). To erase the data, press pand RESET at the same time on the respective deck. “AUTO CAL” for that deck disappears, indicating that the data for the inserted tape type has been erased.

Notes

Automatic calibration works only when both decks are stopped.

You don’t have to select the Dolby NR system when doing automatic calibration since the Dolby NR system does not affect the calibration results.
