MECHANISM ADJUSTMENT
2.1 PREPARATION
2.1.1 Precautions
(1) Disconnect VCR from AC power before soldering.
(2) Avoid imparting stress to wires when disengaging con-
nectors.
(3) Determine and correct the cause of difficulty before pro-
ceeding to adjustments.Do not disturb settings unnec-
essarily.
(4) Use care not to damage tabs,claws,etc during repairs.
(5) Install the cassette housing assembly only when the
mechanism is in the MECHANISM ASSEMBLING
MODE position.
When installing the Front panel assembly,be sure to en-
gage the housing door with the door opener of the cas-
sette housing assembly.
If this is omitted, the cassette door will not open at Eject
and the cassette can not be removed. (See SECTION
1 DISASSEMBLY)
(6
—"
2.1.2 Check without cassette housing assembly.
Mechanism operations can be observed easily by removing
the cassette housing assembly. Use the MECHANISM
SERVICE MODE (See SECTION 1 DISASSEMBLY).
2-1
2.1.3 Manual removal of loaded tape
When the deck enters the emergency mode with cassette
tape loaded and it can not be ejected by pressing the EJECT
button, take out of the cassette tape according to the follow-
ing procedure.
(1) Disconnect the power cord from AC outlet then take out
the Top cover and Front panel assembly.
(2) Turn the loading motor on the Main deck assembly by
hand in the unloading direction to where the pole base
assembly (supply and take-up) is positioned below the
cassette tape. At that time, pay careful attention to the
tape not to get soiled with grease.
(3) Take out 4 screws of the cassette housing assembly (See
SECTION 1 DISASSEMBLY )
(4) Remove the cassette housing with slackened tape and
guard panel of cassette.
(5) Wind up the tape by turning the reel hubíeither supply
or take-up side for convenience) from the bottom of the
cassette,and remove the cassette tape.

2.2.1 Cleaning
Periodic cleaning of the tape transport system is desirable, but
usually not feasible in practice. Therefore, perform cleaning
when a set is brought in for repairs or maintenance. Con-
tamination of the video heads,tape guides and brush can
detract from playback picture quality and in extreme
cases,even damage the tape.For cleaning,use a finemesh
cotton cloth(about the texture of a white dress-shirt) mois-
tened in alcohol. It is recomended to also clean the tape ten-
sion posts and capstan.
e To clean the video heads,press the moistened cloth
gently against the upper drum with fingertip and turn the
drum by hand.
e Do not use a vertical stroke, as this may damage the
heads.
2-3
2.2.2 Lubrication
Oil and grease do not normally require periodic replenishing.
Apply only when replacing lubricated parts{also clean and re-
place lubrication of mating parts if soiled). For parts and
points to apply oil and grease, refer to the exploded views
of the mechanism assembly. Before oiling,clean with
alcohol.Apply one or two drops of oil. Avoid excess oil.
1. Grease is not required for a replacement cassette hous-
ing assembly,as this has been applied at the factory.
NOTE : Stir grease that has been stored for an extended
period.
2.3 INSPECTION AND MAINTENANCE
This product employs rotary and moving parts which wear
out in the course of usage.Periodic inspection, cleaning, lu-
brication and maintenance are therefore important for ensur-
ing maximum performance. Worn parts must also be re-
placed as and when required.
2.3.1 Suggested servicing schedule for main
components
The following table indicates the suggested period for such
service measures as cleaning,lubrication and replacement.
In practice, the indicated periods will vary widely according

26 CHECKUP AND ADJUSTMENT OF MECHANISM
PHASE
2.6.1 Precaution
The rotary encoder and syscon circuit are closely
interrelated. Therefore, the rotary encoder and control cam
connection determines the operations of mechanical parts
such as plates, gears,brakes,etc.Correct positioning of these
parts is essential for smooth tape loading and mechanical
operations.
2.6.2 Loading Arm Assembly (supply,take-up)
(1) Install the supply loading arm assembly and the take-up
loading arm assembly so that their positioning markings
on the respective gear face each other and the holes of
their arms correspond to the holes on the main deck as-
sembly respectively.
(2) After setting the guide rails,engage the pole base assem-
blies with the tip of the loading arms respectively.
Then,enter the mechanism into the unloading mode to
return the pole base assemblies to the front position.
(3) Reassemble the peripheral parts of the guide rail to its
original position.

Confirm that the FM waveform appears as indicated in
Fig.2-7-1.
Set the manual tracking position by simultaneously
pressing the CH “ 4 ” and " V “ buttons.
Operate the tracking adjustment (press the CH buttons
during playback) and set for maximum playback FM
waveform.
By operating the CH button,vary the FM waveform from
maximum to minimum and vice versa to confirm that
the waveform varies nearly in a flat shape as shown in
Fig.2-7-1.
When the FM waveform does not remain flat during
this process, first slightly loosen the set screw located
at the bottom of the guide rollers.Using the guide roller
adjustment tool (Roller driver), adjust the supply and
take-up guide rollers (refer to Fig.2-7-2) to obtain the
correct waveform as indicated in Fig.2-7-3.
By pressing the CH buttons several times,vary the FM
waveform output from maximum to minimum (and vice
versa) gradually,and confirm that the variation proceeds
in flat shape, as shown in Fig.2-7-3.
Next playback the LP stairstep portion of the alignment
tape and adjust the tracking control from maximum to
minimum the FM waveform,confirm that FM waveform
variation 1s always flat.
Record the signal and play it back in both of the SP and
LP mode,confirm that the FM waveform is flat in both
mode.
After adjustments,tighten the set screw of the guide
rollers.
Confirm that the tape wrinking does not occur at the
roller upper or lower limits as indicated in Fig.2-7-4.
