23、hout replacing the acrews and springs, a fine adjustment to the azimuth screw and spring. Please remove the screw-locking bond left on the head base when replacing the azimuth screw. If you wish to readjust the head azimuth, be sure to adjust with adhering the cassette tape closely to the mechanism

24、by pushing the center of cassette tape with your finger. (shown in Fig. 3) 1. Playback the azimuth adjustment portion (8 kHz, -20dB) of the test tape (QZZCFM) in the forward play mode. Vary the azimuth adjustment screw until the output of the R-CH (PB OUT-R) are maximized. 2. Perform the same adjust

25、ment in the reverse play mode. 3. After the adjustment, apply screwlock to the azimuth adjusting screw. 12.1.2. Tape Speed Adjustment (Deck 1/2) 1. Set the tape edit button to “NORMAL” position. 2. Insert the test tape (QZZCWAT) to DECK 2 and playback (FWD side) the middle portion of it. 3. Adjust M
