VCR TEST TAPE INTERCHANGEABILITY TABLE

There are two types of the new allgnment tape CH-1B (for NTSC) and CH-2 (for PAL). On each tape four signals (1)-(4)
are recorded for the times and in the order shown below.

(1) : 8min. → (2) : 2min. → (3) : 5min. → (4) : 5min.

The TTV-MP1 (for M-PAL), TTV-MS1 (for MESECAM) and TTV-S1 (for SECAM) allgnment tapes have the same
contents as the previous tapes.

1) Turn the Power S/W on and eject the Cassette by press­ing the Eject Button.

2) Remove the Top Cover and Plate Assembly Top, visual­ly check if the Gear Cam Hole is aligned with the
Chassis Hole as below Fig. C-2.

3) IF not, rotate the Shaft of the Loading Motor to either
Clockwise or Counterclockwise until the Alignment is
as below Fig. C-2.

4) Remove the Screw which fix es the Deck Mechanism and
Main Frame and confirm if the Gear Cam is aligned with

the Gear Drive as below Fig. C-1(A).

5) Confirm if the Mode S/W on the Main P.C.Board is
aligned as below Fig. C-1(B).

DECK MECHANISM ADJUSTMENT

2. Preparation for Adjustment (To set the
Deck Mechanism to the Loading state
without inserting a Cassette Tape).

1) Unplug the Power Cord from the AC Outlet.

2) Disassemble the Top Cover and Plate Assembly Top.

3) Plug the Power Cord into the AC Outlet.

4) Turn the Power S/W on and push the Lever Stopper (L),(R)
of the Holder Assembly CST to the back for Loading the

Cassette without Tape.
Cover the Holes of the End Sensors at the both sides of the
Bracket Side(L) and Bracket Assembly Door to prevent a
light leak.
Then The Deck Mechanism drives to the Stop Mode.
In this case, The Deck Mechanism can accept inputs of
each mode, however the Rewind and Review Operation
can not be performed for more than a few seconds
because the Take-up Reel Table is in the Stop State and
can not be detected the Reel Pulses.

3 . Checking T orque

The Values are measured by using a Torque Gauge and
Torque Gauge Adaptor with the Torque Gauge affixed.

The Torque reading to measure occurs when the Tape
abruptly changes direction from Fast Forward of Rewind
Mode, when quick bracking is applied to both Reels.

MAINTENANCE/INSPECTION PROCEDURE

The recording density of a VCR(VCP) is much higher than
that of an audio tape recorder.VCR(VCP) components must
be very precise, at tolerances of 1/1000mm, to ensure com­patiblity with other VCRs. If any of these components are
worn or dirty, the symptoms will be the same as if the part is
defective.To ensure a good picture, periodic inspection and
maintenance, including replacement of worn out parts and
lubrication, is necessary.

Schedules for maintenance and inspection are not fixed
because they vary greatly according to the way in which the
customer uses the VCR(VCP), and the environment in which
the VCR(VCP) is used.
But, in general home use, a good picture will be maintained
if inspection and maintenance is made every 1,000 hours.
The table below shows the relation between time used and
inspection period.

Table 1

(1) Grease : Kanto G-311G (Blue) or equivalent
(2) Isopropyl Alcohol or equivalent
(3) Cleaning Patches
(4) Grease : Kanto G-381(Yellow) : Used only for Reel S and

Reel T

(1) Cleaning video head

First use a cleaning tape. If the dir t on the head is too
stubborn to remove by tape, use the cleaning patch.
Coat the cleaning patch with Isopropyl Alcohol. Touch
the cleaning patch to the head tip and gently turn the
head(rotating cylinder) right and left.
(Do not move the cleaning patch vertically. Make sure
that only the buckskin on the cleaning patch comes into
contact with the head. Otherwise, the head may be
damaged.)
Thoroughly dry the head. Then run the test tape. If
lsopropyl Alcohol remains on the video head, the
tape may be damaged when it comes into contact
with the head surface.

(2) Clean the tape transpor t system and drive system, etc,

by wiping with a cleaning patch wetted with Isporopyl
Alcohol.

1 It is the tape transport system which comes into contact

with the running tape.The drive system consists of those
parts which moves the tape.

2 Make sure that during cleaning you do not touch the tape

transport system with the tip of a screw driver and no that
force is that would cause deforming or damage applied to
the system.
