1 GENERAL PRECAUTIONS
1.1.
Safety Precautions
1.2.
Standard for Repair Service
Repair service shall be provided in accordance with repair technology information such as service manual
so as to prevent fires, injury or electric shock, which can be caused by improper repair work.
so as to prevent fires, injury or electric shock, which can be caused by improper repair work.
1. When performing repairs, neither the products nor its parts or components shall be modified.
2. If cable assembly is supplied as the smallest unit when servicing, make sure to replace

1.3.
For Service Technicians
ICs and LSIs are vulnerable to static electricity.
When repairing, the following precautions will help to prevent recurring malfunctions.
When repairing, the following precautions will help to prevent recurring malfunctions.
1. Cover the plastic parts with aluminum foil.
2. Ground the soldering irons.
3. Use a conductive mat on the worktable.
4. Do not grasp IC or LSI pins with bare fingers.

About Lead Free Solder (PbF: Pb free)
Note
• In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder
that contains lead.
• We will use PbF when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn),
Silver (Ag), and Copper (Cu).
• This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and
repair work we suggest using the same type of solder.
Distinction of PbF PCB
• PCBs (manufactured) using lead free solder will have a PbF stamp on the PCB.
Caution
• PbF solder has a melting point that is 50
° - 70 °F, (30 ° - 40 °C) higher than Pb solder.
Please use a soldering iron with temperature control and adjust it to 700
° ± 20 °F (370 ° ± 10 °C).
• Exercise care while using higher temperature soldering irons.: Do not heat the PCB for too long time in order to
prevent solder splash or damage to the PCB.
• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100
°F (600 °C).
• When applying PbF solder to double layered boards, please check the component side for excess solder which may
flow onto the opposite side (See figure below)
1.4.1.
Suggested Pb free solder
We recommend you to use the following solder when re-soldering components for repair. Before using other Pb free solder than the
following solder, make sure to confirm that the solder maker (you use) has the license agreement for Pb free solder.
following solder, make sure to confirm that the solder maker (you use) has the license agreement for Pb free solder.

About RoHS
This product is fully compliant with the national laws transposed from the EU Directive on the restriction of the use of certain
hazardous substances (RoHS) in electrical and electronic equipment, effective 1st July 2006 in the EU countries.
hazardous substances (RoHS) in electrical and electronic equipment, effective 1st July 2006 in the EU countries.
In order for the product to comply with the RoHS Directive, the six particular substances (lead, mercury, cadmium, hexavalent
chromium, polybrominated biphenyls, and polybrominated diphenyl ethers) have been either totally eliminated or limited to the
concentration level below maximum allowed. Consequently spare parts have been changed to RoHS-compliant parts where
applicable.
Due to spare parts application of RoHS legislation, non-compliant spare parts cannot be used to repair compliant products put on
the EU market on or after 1st July 2006. Please therefore make sure to order and use RoHS-compliant spare parts listed in this
manual.
