1.1 Safety Precautions
SECTION 1
PRECAUTION
!
!
Burrs formed during molding may be left over on some parts of the chassis. Therefore,
pay attention to such burrs in the case of preforming repair of this system.
Please use enough caution not to see the beam directly or touch it in case of an
adjustment or operation check.
(No.MA465<Rev.003>)1-7
1.2 Preventing static electricity
Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser
diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.
1.2.1 Grounding to prevent damage by static electricity
Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as laser products.
Be careful to use proper grounding in the area where repairs are being performed.
(1) Ground the workbench
Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the
traverse unit (optical pickup) on it.
(2) Ground yourself
Use an anti-static wrist strap to release any static electricity built up in your body.
(caption)
Anti-static wrist strap
1M
Conductive material
(conductive sheet) or iron plate
(3) Handling the optical pickup
• In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical
pickup are shorted. After replacement, return the shorted parts to their original condition.
(Refer to the text.)
• Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily
destroy the laser diode.
1.3 Handling the traverse unit (optical pickup)
(1) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit.
(2) Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the
replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a
time when attaching it to the connector.
(3) Handle the flexible cable carefully as it may break when subjected to strong force.
(4) It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it.
1.4 Attention when traverse unit is decomposed
*Please refer to "Disassembly method" in the text for the pickup unit.
• Apply solder to the short land before the card wire is disconnected from the connector on the pickup unit.
(If the card wire is disconnected without applying solder, the pickup may be destroyed by static electricity.)
• In the assembly, be sure to remove solder from the short land after connecting the card wire.

1.5 Important for laser products
1.CLASS 1 LASER PRODUCT
2.CAUTION :
(For U.S.A.) Visible and/or invisible class II laser radiation
when open. Do not stare into beam.
(Others) Visible and/or invisible class 1M laser radiation
when open. Do not view directly with optical instruments.
3.CAUTION : Visible and/or invisible laser radiation when
open and inter lock failed or defeated. Avoid direct
exposure to beam.
4.CAUTION : This laser product uses visible and/or invisible
laser radiation and is equipped with safety switches which
prevent emission of radiation when the drawer is open and
the safety interlocks have failed or are defeated. It is
dangerous to defeat the safety switches.
5.CAUTION : If safety switches malfunction, the laser is able
to function.
6.CAUTION : Use of controls, adjustments or performance of
procedures other than those specified here in may result in
hazardous radiation exposure.
!
Please use enough caution not to
see the beam directly or touch it
in case of an adjustment or operation
check.

4.2 Standard measuring conditions
Power supply voltage DC14.4V(10.5 to 16V)
Load impedance 20K ohm (2 Speakers connection)
Output Level Line out 2.5V (Vol. MAX)
4.5 How to connect the extension cable for adjusting
Caution:
Be sure to attach the heat sink and rear bracket onto the power amplifier IC and regulator IC respectively, before supply the power.
If voltage is applied without attaching these parts, the power amplifier IC and regulator IC will be destroyed by heat.

4.4 Dummy load
Exclusive dummy load should be used for AM,and FM.
For FM dummy load, there is a loss of 6dB between SSG output
and antenna input.
The loss of 6dB need not be considered sincedirect reading of
figures are applied in this working standard.

Whether it turns on power and the "PROTECT" display appears are confirmed.
(1) When the "PROTECT" display appears.

·When "PROTECT" is still displayed.
The DC offset has been generated by the reasons other than the improper connection.
Forecast cause: Power AMP is broken.
After parts are exchanged, reset is confirmed pushing again.
(1-2) When "DC2 X" is displayed. (DC ERROR2)
* As for X, the detected number is displayed. (0-4)
* When X is 0, it is unquestionable because the DC offset has never been detected.
When leak of capacitor is detected, it is displayed.
It is confirmed that there is no problem in the capacitor and deletes the error data of EEPROM. (CLR DC2)
It is confirmed that reset is pushed and "PROTECT" is not displayed.
After above-mentioned (1-1) and (1-2) are executed, the conect of the DC offset error is confirmed in the Service mode.
If the part displayed as "DC ERROR" becomes "DC OK", it is unquestionable.
(2) When the "PROTECT" display doesn't appear.
The content of the DC offset error is confirmed in the Service mode.
(2-1) When "DC OK" is displayed, it is unquestionable because the DC offset has not been detected in the past.
(2-2) When "DC ERROR" is displayed, the confirmation similar to (1-1) and (1-2) is done because there is a history that detected
the DC offset error in the past.
