NOTES  ON  CHIP  COMPONENT  REPLACEMENT
• 

Never reuse a disconnected chip component.

• 

Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

FLEXIBLE  CIRCUIT  BOARD  REPAIRING
• 

Keep the temperature of soldering iron around 270 °C during 
repairing.

• 

Do not touch the soldering iron on the same conductor of the 
circuit board (within 3 times).

• 

Be careful not to apply force on the conductor when soldering 
or unsoldering.

SAFETY  CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, 
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.

LEAKAGE  TEST
The AC leakage from any exposed metal part to earth ground and 
from all exposed metal parts to any exposed metal part having a 
return to chassis, must not exceed 0.5 mA (500 microamperes.). 
Leakage current can be measured by any one of three methods.
1.  A commercial leakage tester, such as the Simpson 229 or RCA 

WT-540A. Follow the manufacturers’ instructions to use these 
instruments.

2.  A battery-operated AC milliammeter. The Data Precision 245 

digital multimeter is suitable for this job.

3.  Measuring the voltage drop across a resistor by means of a 

VOM or battery-operated AC voltmeter. The “limit” indication 
is 0.75 V, so analog meters must have an accurate low-voltage 
scale. The Simpson 250 and Sanwa SH-63Trd are examples 
of a passive VOM that is suitable. Nearly all battery operated 
digital multimeters that have a 2 V AC range are suitable. (See 
Fig. A)

CAUTION
Use of controls or adjustments or performance of procedures 
other than those specifi ed herein may result in hazardous radia-
tion exposure.

UNLEADED  SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution:  Some printed circuit boards may not come printed with 

the lead free mark due to their particular size)

Unleaded solder has the following characteristics.
•  Unleaded solder melts at a temperature about 40 °C higher 

than ordinary solder.

 

Ordinary soldering irons can be used but the iron tip has to be 
applied to the solder joint for a slightly longer time.

 

Soldering irons using a temperature regulator should be set to 
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if 

the heated tip is applied for too long, so be careful!

•  Strong viscosity
 

Unleaded solder is more viscous (sticky, less prone to fl ow) 
than ordinary solder so use caution not to let solder bridges 
occur such as on IC pins, etc.

•  Usable with ordinary solder
 

It is best to use only unleaded solder but unleaded solder may 
also be added to ordinary solder.

The laser diode in the optical pick-up block may suffer electro-
static break-down because of the potential difference generated by 
the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also 
use the procedure in the printed matter which is included in the 
repair parts.
The fl exible board is easily damaged and should be handled with 
care.

NOTES  ON  LASER  DIODE  EMISSION  CHECK
The laser beam on this model is concentrated so as to be focused 
on the disc refl ective surface by the objective lens in the optical 
pickup block. Therefore, when checking the laser diode emission, 
observe from more than 30 cm away from the objective lens.

IC901 on the USB-AUDIO board cannot exchange with single. When this 
part is damaged, exchange the complete mounted board.

RELEASING  ANTITHEFT  LOCK  MODE
The disc tray lock function for the antitheft of a demonstration disc 
in the store is equipped.

Procedure:
1.  Press the [

?/1

] button to turn the power on.

2.  Press the [CD/USB] button to select CD function.
3.  Press two buttons of [ENTER] and [

Z

] for 5 seconds or larger 

simultaneously.

4.  The message “UNLOCKED” is displayed on the fl uorescent 

indicator tube, and the disc tray is unlocked.

Note: When “LOCKED” is displayed, the antitheft lock is not released by 

turning power on/off with the [\/1] button.

NOTE  OF  TRANSPORTING  THIS  SET
Transport it after executing “CD SHIP & COLD RESET” accord-
ing to the following procedure when this set is transported.

Procedure:
1.  Press the [

?/1

] button to turn the power on.

2.  Eject the CD.
3.  Press the [CD/USB] button to select CD function
4.  Press three buttons of [

M >

], [ENTER] and [

?/1

] simulta-

neously.

5.  When “STANDBY” and “RESET” appears, the set enters 

standby status.

HOW  TO  OPEN  THE  DISC  TABLE  WHEN  POWER  
SWITCH  TURNS  OFF
Insert a tapering driver into the aperture of the unit bottom, and 
turn it in the direction of the arrow (to OUT direction).

Note: To close the table, turn the tapering driver 
 

in the reverse direction (to IN direction).

NOTE  FOR  GEAR  INSTALLATION
When following gears are installed, it is necessary to phase it.
Please refer to “2-11. GEAR (RV), GEAR (U/D), SWING GEAR” 
(page 12).

Note: When you do the operation check 

of base unit block, please check 
after installing temporary CD on 
the tray.
