Laser component in this product is capableof emitting radiation exceeding the limit forClass 1.

CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.

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 270C

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.

The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.

NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT

This appliance isclassified as a CLASS 1LASER product. Thislabel is located on therear exterior.

The following caution label is located inside the apparatus.

PARTS No.Unleaded solderBoards 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 withthe lead free mark due to their particular size.)

: LEAD FREE MARKUnleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40C higher than

ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350C.Caution: The printed pattern (copper foil) may peel away if theheated tip is applied for too long, so be careful!

Strong viscosityUnleaded solder is more viscous (sticky, less prone to flow) thanordinary solder so use caution not to let solder bridges occur suchas on IC pins, etc.

Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

[When bringing in the equipment for service]In case of repairing, please bring the entire system set([HCD-WZ5,DXA-WZ5],except for the speaker) to the service station.

For the ROM Check, the check sum calculated by the Syscon isoutput, and therefore you must compare it with the specified valuefor confirmation.Following the message, press the [NEXT ] button to go to thenext item, or press the [ PREV] button to repeat the sameoperation again.To quit the diagnosis and return to Check Menu screen, press the[RETURN] key on the remote commander to display Check Menu.

Error occurredIf an error occurred, the diagnosis is suspended and error is displayed.Press the [RETURN] key on the remote commander to quit thediagnosis, or press the [ PREV] button to repeat the same checkwhere an error occurred, or press the [NEXT ] button to continuethe check from the item next to faulty item.

Normally, [10/0] is selected to adjust DVD (single layer), CD andDVD (dual layer) in this order. But, individual items can be adjustedfor the case where adjustment is suspended due to an error. In thismode, the adjustment can be made easily through the operationfollowing the message displayed on the screen.The disc used for adjustment must be the one specified foradjustment.

1-0. ALLPress the [10/0] key on the remote commander, and the servo setdata in EEPROM will be initialized. Then, 1. DVD-SL disc, 2. CDdisc and 3. DVD-DL disc are adjusted in this order.Each time one disc was adjusted, it is ejected. Replace it with thespecified disc following the message. You can finish the adjustmentby pressing the [RETURN] button on the remote commander.

Note: During adjustment of each disc, the measurement for disc type judg-ment is made. As automatic adjustment does not judge the disctype unlike conventional models, take care not to insert wrong typediscs. Also, do not give a shock during adjustment.
