Azimuth Adjustment• Be sure to clean the heads before attempting to make any adjustment.• Be sure both channels (1 and 2) are the same level.(Using a dual-channel oscilloscope)• Be sure both channel's waveform are same for the phase matching.• After completion of the adjustment, use the threadlock (TB-1401B) tosecure the azimuth adjustment screws.LID CLOSE KEYPRESS1. Open the lid. And press the "Lid Close Key" as Fig.1.2. Load a test tape (VTT-738 etc. : 10kHz) in the Deck.3. Press the PLAY button. (Normal playback)4. Use a + tip screwdriver to turn the screw for normal azimuthadjustment so that the left and right outputs are maximized atthe same phase during normal playback. See Fig.2.5. Press the PLAY button. (Reverse playback)6. Use a + tip screwdriver to turn the screw for reverse azimuthadjustment so that the left and right outputs are maximizedat the same phase during reverse playback.7. Adjust so that the waveforms for the left and right channels are in alignment.Fig.1NORMALFig.22. Tape Speed Adjustment• Connect the Frequency Counter to TAPE OUT.1. Insert the test tape (MTT-111N, etc.; 3,000Hz) into the DECK.Fig.3hole for adjustment2. Press the PLAY button. .MOTOR3. Adjust a hole on the motor bottom so that a frequency counter reading of 3,000±5Hzis obtained.See Fig.3.4. Press the STOP button, and eject the test tape.3.
