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 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.

contact our service station or service branch in your area.
Soldering
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.

When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.

This product is classified as a CLASS 1 LASER PRODUCT.
Precaution to be taken when replacing and servicing the
Laser Pickup.
Laser Pickup.
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.
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
any
time.
(5) CAUTION -Use of controls or adjustments, or performance of
procedures other than those specified herein may result in
hazardous radiation exposure.
