SERVICING NOTICES ON CHECKING
1. KEEP THE NOTICES
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.
3. PUT PARTS AND WIRES IN THE
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.
4. PERFORM A SAFETY CHECK AFTER
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.

CLEANING
NOTE
2. TAPE RUNNING SYSTEM
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.
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.)
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.)
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.

Read the following NOTES before starting work.
1. Set to the PLAY mode.
2. Adjust the Tension Adjust until the edge of the Tension
Arm is positioning within 0.5mm range from the
standard line center of Main Chassis.
After this adjustment, confirm that the cut position is
located in "A" area as shown in Fig. 1-2-B. If it is
located in "B" area, adjust again.
3. While turning the S Reel clockwise, confirm that the
edge of the Tension Arm is located in the position
described above.
• 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.
