NOTES ON CHIP COMPONENT REPLACEMENT
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged 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.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree 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)
: LEAD FREE MARK
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.
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.
SAFETY CHECK-OUT (US MODEL)
After correcting the original service problem, perform the following 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)
To Exposed Metal
Parts on Set
CAUTION
Use of controls or adjustments or performance of procedures
other than those specifi ed herein may result in hazardous radia-
tion exposure.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic 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.

Note on DualDiscs
A DualDisc is a two sided disc product which mates DVD recorded material on one side with digital audio material on the other
side. However, since the audio material side does not conform to
the Compact Disc (CD) standard, playback on this product is not
guaranteed.
Music discs encoded with copyright protection
technologies
This product is designed to play back discs that conform to the
Compact Disc (CD) standard. Recently, various music discs
encoded with copyright protection technologies are marketed by
some record companies. Please be aware that among those discs,
there are some that do not conform to the CD standard and may
not be playable by this product.
Note on Multi Session disc
When you play back Multi Session discs with different formats
for each session, the format of the fi rst session is recognized as
the disc type. Tracks in the second and subsequent sessions are
played back if they are the same formats as the fi rst session.

TEST MODE
HCD-ZX66i/ZX99i
[GC TEST MODE]
• This mode is used to check the fl uorescent indicator tube,
LEDs, keys, JOG, VOLUME jog, model, destination and software version.
2. All segments in fl uorescent indicator tube and the LEDs are
lighted up.
3. When you want to enter to the model version and destination
display mode, press [DISC 1] button. The model information
appears on the fl uorescent indicator tube.
4. Each time [DISC 1] button is pressed, the display changes
to display software version of the software creation. The sequence is MC, GC, SYS, CD, CDDM, CDMA, CDMB, BDA,
BDB, ST, TA, TM, and iPod in this order, and returns to the
MC version display.
5. When [DISC 3] button is pressed while the software version is
being displayed, the date of the software creation appears.
When [DISC 3] button is pressed again, the display returns to
the software version display. When [DISC 1] button is pressed
while the date of the software creation is being displayed, the
date of the software creation is displayed in the same order of
software version display.
6. Press [DISC 2] button, the key check mode is activated.
7. In the key check mode, the fl uorescent indicator tube displays
“K 0 J0 V0”.
Turn the [JOG] clockwise; “J” value increases by one. Turn
the [JOG] counterclockwise; “J” value decreases by one. Each
time a button is pressed, “K” value increases. Press their keys
on main unit to check whether the key is detected. However,
once a button has been pressed, it is no longer taken into account.
“V” value increases in the manner of 0, 1, 2, 3 ... if [VOLUME]
knob is turned clockwise, or it decreases in the manner of 0, 9,
8, 7 ... if [VOLUME] knob is turned counterclockwise.
8. When [EX-CHANGE] button is pressed after all segments
in fl uorescent indicator tube and the LEDs light up, alternate
segments in fl uorescent indicator tube would light up. If you
press [EX-CHANGE] button again, another half of alternate
segments in fl uorescent indicator tube would light up. Press

• Due to standardization, replacements in
the parts list may be different from the
parts specifi ed in the diagrams or the com-
ponents used on the set.
• -XX and -X mean standardized parts, so
they may have some difference from the
original one.
• RESISTORS
All resistors are in ohms.
METAL: Metal-fi lm resistor.
METAL OXIDE: Metal oxide-fi lm resistor.
F: nonfl ammable
