21 Safety Precautions1.1. General Guidelines
1. When conducting repairs and servicing, do not attempt to modify the equipment, its parts or its materials.2. When wiring units (with cables, flexible cables or lead wires) are supplied as repair parts and only one wire or some of the
wires have been broken or disconnected, do not attempt to repair or re-wire the units. Replace the entire wiring unit instead.3. When conducting repairs and servicing, do not twist the Faston connectors but plug them straight in or unplug them straight
out.4. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or
damaged by the short circuit.5. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly
installed.6. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
1.1.1. Leakage Current Cold Check1. Unplug the AC cord and connect a jumper between the
two prongs on the plug.2. Measure the resistance value, with an ohmmeter,
between the jumpered AC plug and each exposed metal-lic cabinet part on the equipment such as screwheads,connectors, control shafts, etc. When the exposed metal-lic part has a return path to the chassis, the readingshould be between 1Mohm and 5.2Mohm.When the exposed metal does not have a return path to the chassis, the reading must be .
1.1.2. Leakage Current Hot Check (SeeFigure 1.)
1. Plug the AC cord directly into the AC outlet. Do not usean isolation transformer for this check.
2. Connect a 1.5kohm, 10 watts resistor, in parallel with a0.15F capacitors, between each exposed metallic parton the set and a good earth ground such as a water pipe,as shown in Figure 1.
3. Use an AC voltmeter, with 1000 ohms/volt or more sensi-tivity, to measure the potential across the resistor.
4. Check each exposed metallic part, and measure the volt-age at each point.
5. Reverse the AC plug in the AC outlet and repeat each ofthe above measurements.
6. The potential at any point should not exceed 0.75 voltsRMS. A leakage current tester (Simpson Model 229 orequivalent) may be used to make the hot checks, leakagecurrent must not exceed 1/2 milliamp. In case a mea-surement is outside of the limits specified, there is a pos-sibility of a shock hazard, and the equipment should berepaired and rechecked before it is returned to the cus-tomer.

32 Warning2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically
Sensitive (ES) DevicesSome semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec-trostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors andsemiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damagecaused by electrostatic discharge (ESD).
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on yourbody by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap,which should be removed for potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as alumi-num foil, to prevent electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static (ESD protected)"
can generate electrical charge sufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most
replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or compara-ble conductive material).
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective materialto the chassis or circuit assembly into which the device will be installed.Caution
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise ham less motion such as the brush-
ing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficientto damage an ES device).

42.2. About lead free solder (PbF)Note: Lead is listed as (Pb) in the periodic table of elements.In the information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder.The Lead Free Solder used in our manufacturing process and discussed below is (Sn+Ag+Cu).That is Tin (Sn), Silver (Ag) and Copper (Cu) although other types are available.
This model uses Pb Free solder in its manufacture due to environmental conservation issues. For service and repair work, wedsuggest the use of Pb free solder as well, although Pb solder may be used.
PCBs manufactured using lead free solder will have the PbF within a leaf Symbol PbF stamped on the back of PCB.Caution
Pb free solder has a higher melting point than standard solder. Typically the melting point is 50 ~ 70 F (30~40 C) higher. Pleaseuse a high temperature soldering iron and set it to 700 20 F (370 10 C).
Pb free solder will tend to splash when heated too high (about 1100 F or 600 C).If you must use Pb solder, please completely remove all of the Pb free solder on the pins or solder area before applying Pb sol-der. If this is not practical, be sure to heat the Pb free solder until it melts, before applying Pb solder.
After applying PbF solder to double layered boards, please check the component side for excess solder which may flow onto theopposite side. (see figure below)
Suggested Pb free solderThere are several kinds of Pb free solder available for purchase. This product uses Sn+Ag+Cu (tin, silver, copper) solder. How-ever, Sn+Cu (tin, copper), Sn+Zn+Bi (tin, zinc, bismuth) solder can also be used.
