PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
"MAIN, POWER, DISPLAY, SCART, VIDEO OUT, DIGITAL IN, DVD, SUBWOOFER PWB" of this model employs
lead-free solder.
The LF symbol indicates lead-free solder, and is attached on the PWB and service manuals. The alphabetical character
following LF shows the type of lead-free solder.
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire
solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 C, we recommend you to
As themeltingpoint of lead-free solder(Sn-Ag-Cu) is about 220 C whichishigher than the conventional lead solder
by 40 C,

Lead-free solder contains more tin, and the end of the soldering bit may be easily corrected. Make sure to turn on
and off the
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after
every use
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
Be careful when replacing parts with polarity indication on the PWB silk.

Safety Precaution For Service Manual
WARNINGS
THE AEL (ACCESSIBLE EMISSION LEVEL) OF LASER POWER OUTPUT FOR THIS MODEL IS SPECIFIED TO
BE LOWER THAN CLASS I REQUIREMENTS. HOWEVER, THE FOLLOWING PRECAUTIONS MUST BE OBSERVED
DURING SERVICING TO PROTECT YOUR EYES AGAINTS EXPOSURE TO THE LASER BEAM.
1-WHEN THE CABINET HAS BEEN REMOVED, THE POWER IS TURNED ON WITHOUT A COMPACT DISC,
AND THE PICKUP IS ON A POSITION OUTER THAN THE LEAD-IN POSITION, THE LASER WILL LIGHT FOR
SEVERAL SECONDS TO DETECT A DISC.
DO NOT LOOK INTO THE PICKUP LENS.
2-THE LASER POWER OUTPUT OF THE PICKUP INSIDE THE UNIT AND REPLACEMENT SERVICE PARTS
HAVE ALREADY BEEN ADJUSTED PRIOR TO SHIPPING.
3-NO ADJUSTMENT TO THE LASER POWER SHOULD BE ATTEMPTED WHEN REPLACING OR SERVICING
THE PICKUP.
4-UNDER NO CIRCUMSTANCES LOOK DIRECTLY INTO THE PICKUP LENS AT ANY TIME.
5-CAUTION - USE OF CONTROLS OR ADJUSTMENTS, OR PERFORMANCE OF PROCEDURES OTHER THAN

Since this DVD system incorporates the following
automatic adjustment functions, readjustment is
not needed when replacing the pickup. Therefore,
different PWBs and pickups can be combined
freely. Each time a disc is changed, these
adjustments are performed automatically.
Therefore, playback of each disc can be performed
under optimum conditions.
Items adjusted automatically
1) Offset adjustment (The offset voltage between the
head amplifier output and the VREF reference
voltage is compensated inside the IC.)
3) Gain adjustment (The gain is compensated inside
the IC so that the loop gain at the gain crossover
frequency will be 0 dB.)
* Focus gain adjustment
* Tracking gain adjustment
