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.

• Adjustment Procedure
1. Insert the PAL SP Test Tape (TTV-P1) and play.
Note - Adjust the distance of X, pressing the Tracking(+) or Tracking(-) when the “ATR” is blink after the
PAL SP Test Tape is inserted.
2. Connect the CH1 of the oscilloscope to the H/SW (W317, 318) and CH2 to the Video Out for the VCR.
3. Trigger the mixed Video Signal of CH2 to the CH1 H.SW (W317, W318), and then check the distance (time
difference), which is from the selected A(B) Head point of the H.SW(W317, W318) signal to the starting
point of the vertical synchronized signal, to 6.5H ± 0.5H (412µs, 1H=63.5µs).

(Mecanism Condition)
• Play an alignment tape
(with 6H 3kHz Color Bar
Signal)
NOTES:
Play an alignment tape then change the operating mode to
CUE or REV and confirm if the unit meets the above listed
specifications.
1) CUE is fast forward mode (FF)
2) REV is the rewind mode (REW)
3) Referenced to the Play mode
8-2.Check for tape curling or jamming
Test Equipment/ Fixture

• T-120 Tape
Specification
Test Conditions
VCR(VCP)
(Mecanism
StateCondition)
• Be sure there is no tape jamming or curling
at the begining, middle or end of the tape.
• Run the CUE, REV play mode at the
beginning and the end of the tape.
Checking Procedure
1) Confirm that the tape runs smoothly around the roller
guides, drum and A/C head assemblies while abruptly
changing operating modes from Play to CUE or REV.
This is to be checked at the begining, middle and end
sections of the cassette.
2) Confirm that the tape passes over the A/C head assembly as indicated by proper audio reproduction and proper tape counter performance.

MAINTENANCE/INSPECTION PROCEDURE
1 Check before starting repairs
The following faults can be remedied by cleaning and oiling.
Check the needed lubrication and the conditions of cleanliness in the unit.
Check with the customer to find out how often the unit is
used, and then determine that the unit is ready for inspection
and maintenance. Check the following parts.

MAINTENANCE/INSPECTION PROCEDURE
4. Supplies Required for Inspection and
Maintence
2. Required Maintenance
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.
(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
5) Maintenance Procedure
5-1) Cleaning
3. Scheduled Maintenance
(1) Cleaning video head
First use a cleaning tape. If the dirt 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 transport system and drive system, etc,
by wiping with a cleaning patch wetted with Isporopyl
Alcohol.
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.

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.
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.

5-2) Greasing
(1) Greasing guidelines
Apply grease, with a cleaning patch. Do not use excess
grease. It may come into contact with the tape transport
or drive system. Wipe any excess and clean with clean
ing patch wetted in Isopropyl Alcohol.
