SERVICE NOTICE ON CHECKING

1. KEEP THE NOTICES 3. PUT PARTS AND WIRES IN THE

As for the places which need special attentions,
they are indicated with the labels or seals on the
cabinet, chassis and parts. Make sure to keep the
indications and notices in the operation manual.

2. USE THE DESIGNATED PARTS

The parts in this equipment have the specific
characters of incombustibility and withstand
voltage for safety. Therefore, the part which is
replaced should be used the part which has
the same character.
Especially as to the important parts for safety
which is indicated in the circuit diagram or the
table of parts as a mark, the designated
parts must be used.

ORIGINAL POSITION AFTER
ASSEMBLING OR WIRING

There are parts which use the insulation
material such as a tube or tape for safety, or
which are assembled in the condition that
these do not contact with the printed board.
The inside wiring is designed not to get closer
to the pyrogenic parts and high voltage parts.
Therefore, put these parts in the original
positions.

PERFORM A SAFETY CHECK AFTER

4.
SERVICING

Confirm that the screws, parts and wiring which
were removed in order to service are put in the
original positions, or whether there are the
portions which are deteriorated around the
serviced places serviced or not. Check the
insulation between the antenna terminal or
external metal and the AC cord plug blades.
And be sure the safety of that.

2. CONFIRMATION AND ADJUSTMENT
OF TAPE RUNNING MECHANISM

Ta pe Running Mechanism is adjusted precisely at the
factory. Adjustment is not necessary as usual. When you
replace the parts of the tape running mechanism because
of long term usage or failure, the confirmation and adjust­ment are necessary.

2-1: GUIDE ROLLER

1.

Playback the VHS Alignment Tape (JG001C or JG001E).

(Refer to SERVICING FIXTURE AND TOOLS)

2.

Connect CH-1 of the oscilloscope to TP103 (Envelope)
and CH-2 to TP102 (SW Pulse).
Trigger with SW Pulse and observe the envelope. (Refer

3.

to Fig. 2-1-A)

4.

When observing the envelope, adjust the Adjusting
Driver (JG005) slightly until the envelope will be flat.
Even if you press the Tracking Button, adjust so that
flatness is not moved so much.
Adjust so that the A : B ratio is better than 3 : 2 as shown

5.
in Fig. 2-1-B, even if you press the Tracking Button to
move the envelope (The envelope waveform will begin to
decrease when you press the Tracking Button).

CLEANING

NOTE

After cleaning the heads with isopropyl alcohol, do not
run a tape until the heads dry completely. If the heads
are not completely dry and alcohol gets on the tape,
damage may occur.

1. AUDIO CONTROL HEAD

Clean the Audio Control Head with the cotton stick
soaked by alcohol. Clean the full erase head in the
same manner. (Refer to the figure below.)

2. TAPE RUNNING SYSTEM

When cleaning the tape transport system, use the
gauze moistened with isopropyl alcohol.

3. CYLINDER

Wrap a piece of chamois around your finger. Dip it in
isopropyl alcohol. Hold it to the cylinder head softly.
Turn the cylinder head counterclockwise to clean it (in
the direction of the arrow). (Refer to the figure below.)

NOTE

Do not exert force against the cylinder head. Do not move
the chamois upward or downward on the head.
