1 Safety Precautions
1.1. General Guidelines
1. When servicing, observe the original lea ress. If a short circuit is foun , replace all parts which have been overheate or
amage by the short circuit.
2. After servicing, see to it that all the protective evices such as insulation barriers, insulation papers shiel s are properly
installe .
3. After servicing, make the following leakage current checks to prevent the customer from being expose to shock hazar s.
4. When servicing, observe the original lea ress. If a short circuit is foun , replace all parts which have been overheate or
amage by the short circuit.
5. After servicing, see to it that all the protective evices such as insulation barriers, insulation papers shiel s are properly
installe .
6. After servicing, make the following leakage current checks to prevent the customer from being expose to shock hazar s.
1.2. Touc -Current C eck
1. Plug the AC cor irectly into the AC outlet. Do not use an isolation transformer for this check.
2. Connect a measuring network for touch currents between each expose metallic part on the set an a goo earth groun
such as a water pipe, as shown in Figure 1.
3. Use Leakage Current Tester (Simpson 228 or equivalent) to measure the potential across the measuring network.
4. Check each expose metallic part, an measure the voltage at each point.
5. Reserve the AC plug in the AC outlet an repeat each of the above measure.
6. The potential at any point (TOUGH CURRENT) expresse as voltage U1 an U2, oes not excee the following values:
For a. c.: U1 = 35 V (peak) an U2 = 0.35 V (peak);
For . c.: U1 = 1.0 V,
Note:
The limit value of U2 = 0.35 V (peak) for a. c. an U1 = 1.0 V for . c. correspon to the values 0.7 mA (peak) a. c. an 2.0
mA . c.
The limit value U1 = 35 V (peak) for a. c. correspon to the value 70 mA (peak) a. c. for frequencies greater than 100 kHz.
7. In case a measurement is out of the limits specifie , there is a possibility of a shock hazar , an the equipment shoul be
repaire an rechecke before it is returne to the customer.

2 Warning
2.1. Prevention of Electrostatic Disc arge (ESD) to Electrostatically
Sensitive (ES) Devices
Some semicon uctor (soli state) evices can be amage easily by static electricity. Such components commonly are calle Elec
trostatically Sensitive (ES) Devices. Examples of typical ES evices are integrate circuits an some fiel -effect transistors an
semicon uctor [chip] components. The following techniques shoul be use to help re uce the inci ence of component amage
cause by electrostatic ischarge (ESD).
1. Imme iately before han ling any semicon uctor component or semicon uctor-equippe assembly, rain off any ESD on your
bo y by touching a known earth groun . Alternatively, obtain an wear a commercially available ischarging ESD wrist strap,
which shoul be remove for potential shock reasons prior to applying power to the unit un er test.
2. After removing an electrical assembly equippe with ES evices, place the assembly on a con uctive surface such as alumi
num foil, to prevent electrostatic charge buil up or exposure of the assembly.
3. Use only a groun e -tip sol ering iron to sol er or unsol er ES evices.
4. Use only an anti-static sol er removal evice. Some sol er removal evices not classifie as [anti-static (ESD protecte )] can
generate electrical charge sufficient to amage ES evices.
5. Do not use freon-propelle chemicals. These can generate electrical charges sufficient to amage ES evices.
6. Do not remove a replacement ES evice from its protective package until imme iately before you are rea y to install it. (Most
replacement ES evices are package with lea s electrically shorte together by con uctive foam, aluminum foil or compara
ble con uctive material).
7. Imme iately before removing the protective material from the lea s of a replacement ES evice, touch the protective material
to the chassis or circuit assembly into which the evice will be installe .
Caution
Be sure no power is applie to the chassis or circuit, an observe all other safety precautions.
8. Minimize bo ily motions when han ling unpackage replacement ES evices. (Otherwise ham less motion such as the brush
ing together of your clothes fabric or the lifting of your foot from a carpete floor can generate static electricity (ESD) sufficient
to amage an ES evice).

Note: Lead is listed as (Pb) in t e periodic table of elements.
In t e information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder.
T e Lead Free Solder used in our manufacturing process and discussed below is (Sn+Ag+Cu).
T at is Tin (Sn), Silver (Ag) and Copper (Cu) alt oug ot er types are available.
This mo el uses Pb Free sol er in it's manufacture ue to environmental conservation issues. For service an repair work, we'
suggest the use of Pb free sol er as well, although Pb sol er may be use .
PCBs manufacture using lea free sol er will have the PbF within a leaf Symbol PbF stampe on the back of PCB.
Caution
• Pb free sol er has a higher melting point than stan ar sol er. Typically the melting point is 50 ~ 70 °F (30~40 °C) higher. Please
use a high temperature sol ering iron an set it to 700 ± 20 °F (370 ± 10 °C).
• Pb free sol er will ten to splash when heate too high (about 1100 °F or 600 °C).
If you must use Pb sol er, please completely remove all of the Pb free sol er on the pins or sol er area before applying Pb sol
er. If this is not practical, be sure to heat the Pb free sol er until it melts, before applying Pb sol er.
• After applying PbF sol er to ouble layere boar s, please check the component si e for excess sol er which may flow onto the
opposite si e. (see figure below)

remove all of the ^ 1П\
excess sol er

\
sol er
Suggested Pb free solder
There are several kin s of Pb free sol er available for purchase. This pro uct uses Sn+Ag+Cu (tin, silver, copper) sol er. How
ever, Sn+Cu (tin, copper), Sn+Zn+Bi (tin, zinc, bismuth) sol er can also be use .
