I have done short video to show how I do DRAGON calibration. It should pretty simple if you your deck has no issues.

.. and this part.. is generated by AI.. but checked by me!

Preparation:
Set the deck to REC PAUSE mode. Turn off Dolby, MPX, and Subsonic filters. Select the correct tape type (I: EX, II: SX, IV: ZX).

Level Calibration (400 Hz):
Press the 400Hz tone button.
Adjust the recording level (left and right) so the VU meters read 0 dB.

Bias Calibration (15 kHz - Manual Method):
Press the 15kHz tone button.
Adjust the bias knobs for both channels so the VU meter reads 0 dB (or sometimes -20dB depending on the specific model variation/calibration tape used, aiming for the flattest response).

Finalize: Switch back to 400Hz to verify it is still at 0dB. If not, readjust and repeat.
