Example:

Indicates lead-free solder of tin, silver and copper.

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.

Lead-free wire solder for servicing

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 use a dedicated soldring 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  C which is higher than the conventional lead 
solder by 40  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.

"MAIN, POWER, DISPLAY, SPEAKER/JACK, AUDIO IN, USB, iPod, KEY 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.

This product is classified as a CLASS 1 LASER PRODUCT.

The AEL (Accessible Emission Level) of Laser Power Output is 
less than Class 1 but the laser component is capable of emitting 
radiation exceeding the limit for Class 1. Therefore it is important 
that the following precautions must be observed during servicing 
to protect your eyes against 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 those specified herein may result in   

 

hazardous radiation exposure.
