1.Mechanism Alignment Position Check
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 fixes 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).
6) Remount the Deck Mechanism on the Main P.C.Board and check each operation.

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 CSTto 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 Torque
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 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.
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.
