SERVICE
MANUAL

*SAFETY INSTRUCTIONS
PRECAUTIONS DURING SERVICING
1. Parts identified by the .' (%) symbol are critical for
safety. Replace them only with the parts number speci-
fied.
2.\n addition to safety, other parts and assemblies are
specified for conformance with such regulations as
those applying to spurious radiation.
These must also be replaced only with the specified
replacements.
Examples: RF converters, tuner units, antenna selec-
tor switches, RF cables, noise blocking capacitors,
noise blocking filters, etc.
3. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
4. Use specified insulating materials for hazardous live
parts. Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers (insulating barriers)
4) Insulation sheets for transistors
5) Plastic screws for fixing micro switches
5. When replacing AC primary side components (trans-
formers, power cords, noise blocking capacitors, etc.),
wrap the ends of the wires securely around the termi-
nals before soldering.
oho I*
6. Make sure that wires do not contact heat producing
parts (heat sinks, oxide metal film resistors, fusible
resistors, etc.).
7. Check that replaced wires do not contact sharp edged
or pointed parts.
8. Also check areas surrounding repaired locations.
9. Make sure that foreign objects (screws, soider drop-
lets, etc.) do not remain inside the set.
MAKE YOUR CONTRIBUTION TO PRO-
TECT THE ENVIRONMENT
Used batteries with the ISO symbol for recy- LAY.
cling as well as small accumulators (recharge-
able batteries), mini-batteries (cells) and starter
batteries should not be thrown into the garbage can.
Please leave them at an appropriate depot. All other
household batteries can be thrown out with the household
waste.
SAFETY CHECK AFTER SERVICING
After servicing, make measurements of leakage-current
or resistance in order to determine that exposed parts are
acceptably insulated from the supply circuit.
The leakage-current measurement should be done be-
tween accessible metal parts (such as chassis, ground
terminal, microphone jacks, signal input/output connec-
tors, etc.) and the earth ground through a resister of 1500
ohms paralleled with a 0.15 uF capacitor, under the unit's
normal working conditions.
The leakage-current should be less than 0.5 mA rms AC.
The resistance measurement should be done between
accessible exposed metal parts and power cord plug
prongs with the power switch (if included) “ON”. The
resistance should be more than 2.2 M Ohms.
PRECAUTIONS IN REPAIRING
When repairing or adjusing the unit, please note the
following points.
1. Do not put excessive pressure on the mechanical part
(operation part), including the pick-up block, as ex-
tremely high mechanical precision is required in these
parts.
2. When the base is removed for repair or adjustment,
make sure that there are no metal obiects in the nar-
row gap between the P.C. board or the mecha parts
and the base.
3. The Micro-Computer and the CD signal processing ICs
can be damaged by static electricity or leakage from a
soldering iron during repairing. While soldering, please
take the precautions against leakage as in the illustra-
tion.
2” GNO
4. Do not loosen any screws in the pick-up block.
When handling the pick-up block, please refer to the
points to NOTE when replacing the pick up block.
5. To avoid hazardous invisible Laser Radiation, DO NOT
look at the Laser Beam (Objective lens) directly.
6. On models for some countries, laser warning labels
are affixed on the unit and inside of the unit, as shown
below.For your safety, read these labels carefully when
repairing or adjusting the unit.

PRECAUTION BEFORE REPAIRING THE
UNIT
[ABOUT THE POWER SUPPLY]
When repairing, refer to the following procedures to sup-
ply the power to each unit.
* TP-550/650
Connect the two black and red CONTROL CONNEC-
TORS to the AX-550/650. Then while pressing the TIMER
ON/OFF and TIMER MEMORY buttons on the front panel
simultaneously, connect the AC POWER CORD on the
AX-550/650 to the AC power outlet.
* CD-650
Power for the CD-650 is supplied from the AX-550/650
though the TP-550/650.
Therefore, when repair of the CD-650 is necessary, re-
pair should be made togethir with the AX-550/650 and
TP-550/650.
« AX-550/650
While pressing the » and < buttons simultaneously on
the AX-550/650, connect the AC power cord to the AC
power outlet.
