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

PREVENTIVE CHECKS AND SERVICE INTERVALS

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

Wrap a piece of chamois around your finger. Dip it in
isopropyl alcohol and clean the audio control head by
wiping it horizontally. 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.
Use the chamois one by one.

1. CONFIRMATION AND ADJUSTMENT

Read the following NOTES before starting work.

••Place an object which weighs between 450g~500g on
the Cassette Tape to keep it steady when you want to
make the tape run without the Cassette Holder. (Do not
place an object which weighs over 500g.)
When you activate the deck without the Cassette
Holder, short circuit between TP1001 and GND. (Refer

to ELECTRICAL ADJUSTMENT PARTS LOCATION
GUIDE) In this condition the BOT/EOT/Reel Sensor will

not function.

taking care not to scratch the drum, as shown in Fig. 1-
1-A.

3.

Confirm that "A" of the reel disk is lower than "B" of the
reel disk height adjustment jig (JG024A) , and is higher
than "C". If it is not enough height, adjust to 10(+0.2, -0)
mm with the height adjustment washer.

4.

Adjust the other reel in the same way.
