1. Employing lead-free solder
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free wire solder

Lead-free wire solder for servicing
PRECAUTIONS FOR USING LEAD-FREE SOLDER
“MAIN, DISPLAY, KEY/JACK, BLUETOOTH, USB, SMPS 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.
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.
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
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 use a dedicated soldering bit, if you are not familiar
with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220
o
o
C which is higher than the conventional lead solder
by 40
o
C, and as it has poor solder wet ability, you may be apt to keep the soldering bit in contact with the PWB for
extended period of time. However, since the land may be peeled off or the maximum heat-resistance temperature of
parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady soldering condition.
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 power of the bit as required.
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 of it.
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.

CHAPTER 1. GENERAL DESCRIPTION
[1] Safety Precaution For Service Manual
This product is classified as a CLASS 1 LASER PRODUCT.
Precaution to be taken when replacing and servicing the Laser Pickup.
Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class 1 Requirements.
However, the following precautions must be observed during servicing to protect your eyes against exposure to the Laser beam.
However, the following precautions must be observed during servicing to protect your eyes against exposure to the Laser beam.
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.
The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior to shipping.
No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
Under no circumstances look directly into the Pickup Lens at any time.
CAUTION -Use of controls or adjustments, or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
