SAFETY CHECK-OUT
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)

HCD-DZ280/DZ680/HDZ284/HDZ485
Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.
This appliance is classifi ed as a CLASS 1 LASER product. This marking is located on the rear or bottom exterior.
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 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 discs
This product is designed to playback discs that conform to the Compact Disc (CD) standard. DualDiscs and someofthe music discs encoded withcopyrightprotection technologiesdo notconform to the Com pact Disc (CD) standard, t herefore, these discs may not be playable by this product.
Example of discs that the system cannot play
The system cannot play the following discs:
• CD-ROM/CD -R/CD-RW other than those recorded in the formats listed on page 6
• CD-ROM recorded in PHOTO CD format
• Data part of CD-Extra
•CDGraphicsdisc
• DVD Audio
• DATA DVD that does not contain MP3 files,JPEG image files, DivX video files, or MPEG4 video files
• DVD-RAM
•Blu-rayDisc
Also, the system cannot play the following discs:
• A DVD VIDEO with a different region code (page 8)
• A disc that has a non-standard shape (e.g., car d, heart)
• A disc with paper or stickers on it
• A disc that has the adhesive of c el lophane tape or a sticker still left on i t
Note about CD-R/CD-RW/DVD-R/DVD-RW/DVD+R/DVD+RW
In somecases,CD-R/CD-RW/DVD-R/DVD-RW/DVD+R/DVD+RW cannot beplayed on thissystem due to the recording qual ity or physical condition of the disc, or t he character i st ics of the recording device and authoring software. The discwill notplay if ithas not beencorrectly finalized. Form ore information,refer tothe operating instructions for the recording device. Note that some playback functions may not work with some DVD+RWs/DVD+Rs, even if they have been correctly finalized. In this case, view the disc bynormalplayback.Also some DATA CDs/DATA DVDs created in Packet Write format cannot be played.
About Multi Session CD
• This system can play a Multi Session CD when an MP3 file is contained in the first session. Any subsequent MP3 fil es recorded in later ses si ons can also be played back.
• This system can play a Multi Session CD when a JPEG image file is contained in the first session. Any subse quent JPEG image fil es recorde d i n later sessions can also b e played back.
• If MP3 files and JPEG image files in music CD format or video CD format are recorded in the first session, only the first sess ion will be played back.

SERVICING NOTES

SECTION 1
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.
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.
LASER DIODE AND FOCUS SEARCH
1. Open the case and turn POWER on with no disc inserted.
2. Confi rm that the following operation is performed while observing the objecting lens from the clearance of DVD mechanism deck.
1) Confi rm that laser beam is spread.
2) Up and down motion of the objective lens. (2 times)
