1-A. Preliminary/Final Checking and
Alignment of Tape Path
Purpose:
To make sure that the tape path is well stabilized.
Symptom of Misalignment:
If the tape path is unstable, the tape will be damaged.
Note: Do not use an Alignment Tape for this procedure. If the unit is not correctly aligned, the tape may be damaged.
1. Playback a blank cassette tape and check to see that the tape runs without creasing at Guide Rollers
[2] and [3], and at points A and B on the lead surface. (Refer to Fig. M3 and M4.)
2. If creasing is apparent, align the height of the guide rollers by turning the top of Guide Rollers [2] and
[3] with a Guide Roller Adj. Screwdriver. (Refer to

1-B. X Value Alignment
Purpose:
To obtain maximum PB FM envelope signal at the preset position of the Tracking Control Circuit, align the
Horizontal Position of the ACE Head.
Symptom of Misalignment:
If the Horizontal Position of the ACE Head is not properly aligned, maximum PB FM envelope cannot be obtained at the preset position of the Tracking Control
Circuit.
1. Connect the oscilloscope to TP301 (C-PB) and
TP503 (CTL) on the Main CBA. Use TP504 (RF-
SW) as a trigger.
2. Playback the Gray Scale of the Alignment Tape
(FL6NS8) and confirm that the PB FM signal is present.
3. Set the Tracking Control Circuit to the preset position by pressing CH UP button and then “PLAY” button on the unit. (Refer to note on bottom of page
2-3-4.)
4. Use the Flat Screwdriver so that the PB FM signal at TP301 (C-PB) is maximum. (Fig. M6)

6. Set the Tracking Control Circuit to the preset position by pressing CH UP button and then “PLAY” button on the unit.
1-C. Checking/Adjustment of Envelope
Waveform
Purpose:
To achieve a satisfactory picture, adjust the Guide
Rollers so that the PB FM envelope becomes as flat as possible.
Symptom of Misalignment:
If the envelope output is poor, noise will appear in the picture. The tracking will then lose precision and the playback picture will be distorted by any slight variation of the Tracking Control Circuit.
1. Connect the oscilloscope to TP301 (C-PB) on the
Main CBA. Use TP504 (RF-SW) as a trigger.
2. Playback the Gray Scale on the Alignment Tape
(FL6NS8). Set the Tracking Control Circuit to the preset position by pressing CH UP button and then
“PLAY” button on the unit. Adjust the height of
Guide Rollers [2] and [3] (Fig. M3, Page 2-3-3) watching the oscilloscope display so that the envelope becomes as flat as possible. To do this adjustment, turn the top of the Guide Roller with the
Guide Roller Adj. Screwdriver.
3. If the envelope is as shown in Fig. M7, adjust the height of Guide Roller [2] (Refer to Fig. M3) so that the waveform looks like the one shown in Fig. M9.
4. If the envelope is as shown in Fig. M8, adjust the height of Guide Roller [3] (Refer to Fig. M3) so that the waveform looks like the one shown in Fig. M9.
5. When Guide Rollers [2] and [3] (Refer to Fig. M3) are aligned properly, there is no envelope drop
2-3-4
Fig. M9
Envelope is adjusted properly. (No envelope drop)
Fig. M10
Note: Upon completion of the adjustment of Guide
Rollers [2] and [3] (Refer to Fig. M3), check the X
Value by pushing the CH UP or DOWN buttons on the unit alternately, to check the symmetry of the envelope. Check the number of pushes to ensure preset position. The number of pushes of the CH UP button on the unit to achieve 1/2 level of envelope should match the number of pushes of the CH DOWN button on the unit from center. If required, redo the “X Value
Alignment.”
D5P4HSMA
1-D. Azimuth Alignment of Audio/Control/ Erase Head
Purpose:
To correct the Azimuth alignment so that the Audio/
Control/Erase Head meets tape tracks properly.
Symptom of Misalignment:
If the position of the Audio/Control/Erase Head is not properly aligned, the Audio S/N Ratio or Frequency
Response will be poor.
1. Connect the oscilloscope to the audio output jack on the rear side of the deck.
2. Playback the alignment tape (FL6NS8) and confirm that the audio signal output level is 8kHz.
3. Adjust Azimuth Adj. Screw so that the output level on the AC Voltmeter or the waveform on the oscilloscope is at maximum. (Fig. M6)
Note: Upon completion of the adjustment of Azimuth
Adj. Screw, check the X Value by pushing the CH UP or DOWN buttons on the unit alternately, to check the symmetry of the envelope. Check the number of pushes to ensure preset position. The number of pushes of the CH UP button on the unit to achieve 1/2 level of envelope should match the number of pushes of the CH DOWN button on the unit from center. If required, redo the “X Value Alignment.”
1-E. Checking and Alignment of Tape
Path during reversing
Purpose:
To make sure that the tape path is well stabilized during reversing.
Symptom of Misalignment:
If the tape path is unstable during reversing, the tape will be damaged.
Note: Do not use an Alignment Tape for this procedure. If the unit is not correctly aligned, the tape may be damaged.
1. Insert a blank cassette tape into the tray and set the unit to REV. Then confirm if the tape has been curled up or bent at the Take-up Guide Post[4] or
REV Post[5]. (Refer to Fig. M11 and M12.)
2. When the tape has been curled up or bent, turn the alignment screw to adjust the height of REV Post.

ALIGNMENT PROCEDURES OF MECHANISM
The following procedures describe how to align the individual gears and levers that make up the tape loading/unloading mechanism. Since information about the state of the mechanism is provided to the
System Control Circuit only through the Mode Switch, it is essential that the correct relationship between individual gears and levers be maintained.
All alignments are to be performed with the mech-
anism in Eject mode, in the sequence given. Each procedure assumes that all previous procedures have been completed.
Alignment 1
Loading Arm (SP) and (TU) Assembly
Install Loading Arm (SP) and (TU) Assembly so that their triangle marks point to each other as shown in
Fig. AL2.
Alignment 2
Mode Gear
Keeping the two triangles pointing at each other, install the Loading Arm (SP) Assembly so that the last tooth of the gear meets the most inside teeth of the Mode
Gear. See Fig. AL2.
IMPORTANT:
If any one of these alignments is not performed properly, even if off by only one tooth, the unit will unload or stop and it may result in damage to the mechanical or electrical parts.
